A continuous conducting path consisting of some electric components connected between the two terminals of a battery is called an electric circuit.

An electric circuit generally consisting of a bulb 1. Unit of current is ampere A. When 1 coulomb of charge flows through a conductor Ncert Solutions Class 10th Physics Electricity Network in 1 second, then the current flowing through the conductor is called 1 ampere. A battery consisting of one or more electric cells is used to maintain a potential difference across a conductor. Potential difference between two points in a current-carrying conductor is said to be 1 volt if 1 joule of work is done to carry a charge of 1 coulomb from one point to the other, i.

Will current flow more easily through a thick wire or a thin wire of the same material when connected to the same source? The current flows more easily through a thick wire than through a thin wire. This is due to the reason that the resistance R of a thick wire of large area of cross-section, A is less than that of a thin wire of small A as.

Let the resistance of an electrical component remain constant while the potential difference across the two ends of the component decreases to half its former value. What change will occur in the current through it? When the potential difference across the two ends of the electrical component becomes half its former value, the current through it also becomes half. Why are the coils of electric toasters and electric irons made of an alloy rather than a pure metal?

Alloys are used for making the coils in electric toaster and electric iron because alloys have higher melting point than pure metals. So, the coils made from alloys do not melt or get deformed and alloys do not get oxidised or burn readily at high temperatures. Use the data in Table 1 Ncert Solutions Class 10th Physics Electricity Service B Which material is the best conductor?

The schematic circuit diagram is shown below:. What would be the reading in the ammeter and the voltmeter? What is the resistance of an electric iron connected to the same source that takes as much current as all three appliances and what is the current through it? What are the advantages of connecting electrical devices in parallel with the battery instead of connecting them in series? A When a number of electrical devices are connected in parallel, each device gets the same potential difference as provided by the battery and it keeps on working even if other devices fail.

This is not so in case the devices are connected in series because when one device fails, the circuit is broken and all devices stop working. B Parallel circuit is helpful when each device has different resistance and requires different current for its operation as in this case the current divides itself through different devices.

This is not so in series circuit where same current flows through all the devices, irrespective of their resistances. B By connecting all the three resistances in parallel. The cord of an electric heater is made of thick copper wire and has much lower resistance than its element. For the same current I flowing through the cord and the element, heat produced I 2 Rt in the element is much more than produced in the cord.

Consequently, the element becomes very hot and glows whereas the cord does not become hot and as such does not glow. Compute the heat generated while transferring coulombs of charge in one hour through a potential difference of 50 V. Calculate the heat generated in 30 s.

Rate at which energy is delivered by a current is called electric power. Electric power is determined by A The potential difference across the conductor in volts B The current in amperes. A piece of wire of resistance R is cut into five equal parts. These parts are then connected in parallel.

Which of the following terms does not represent electrical power in a circuit? Thus, option B is the correct answer. An electric bulb is rated V and W. Two conducting wires of the same material and of equal lengths and equal diameters are first connected in series and then in parallel in an electric circuit. The ratio of the heat produced in series and parallel combinations would be A 1 : 2 B 2 : 1 C 1 : 4 D 4 : 1.

Since both the wires are made of the same material and have equal lengths and equal diameters, these have the same resistance. Let it be R. A voltmeter is always connected in parallel across the points between which the potential difference is to be determined.

A copper wire has a diameter of 0. How much of this wire would be required to make a 10 ohm coil? How much does the resistance change if the diameter is doubled? The values of current, I , Class 10th Physics Chapter 1 Ncert Solutions Map flowing in a given resistor for the corresponding values of potential difference, V , across the resistor are given here : I ampere 0. The V � I graph is as shown in figure.

Therefore, The value of R obtained from the graph depends upon the accuracy with which the graph is plotted. When a 12 V battery is connected across an unknown Ncert Solutions Class 10th Physics Electricity Engineer resistor, there is a current of 2. Find the value of the resistance of the resistor. A battery of 9 V is connected in series with resistors of 0. Let there be n resistors in parallel. A The resistance of the combination is higher than each of the resistances. Several electric bulbs designed to be used on a V electric supply line, are rated 10 W.

How many lamps can be connected in parallel with each other across the two wires of V line if the maximum allowable current is 5A? In a parallel combination, each bulb has the voltage equal to that of the main line, and the sum of the currents drawn by each bulb would be equal to the allowable current. What are the currents in the three cases? Two lamps, one rated W at V, and the other 60 W at V, are connected in parallel to electric mains supply.

What current is drawn from the line if the supply voltage is V? Since both the bulbs are connected in parallel and to a V supply, the voltage across each bulb is V.

Calculate the rate at which heat is developed in the heater. Explain the following : A Why is tungsten used almost exclusively for filament of electric lamps? B Why are the conductors of electric heating devices, such as toasters and electric ions, made of an alloy rather than a pure metal? C Why is the series arrangement not used for domestic circuits? D How does the resistance of a wire vary with its area of cross-section.

E Why are copper and aluminium wires usually employed for electricity transmission. B The resistivity of an alloy is generally higher than that of pure metals of which it is made of.

C In series arrangement, if any one of the applicances fails or is switched off, all the other applicances stop working because the same current is passing through all the appliances.

E Copper and aluminium wires possess low resistivity and as such are generally used for electricity transmission.
