A piece of wire of resistance R is cut into five equal parts. These parts are then connected in parallel. Solution: Resistance is proportional to length. Resistance of piece of wire is R. Which of the following terms does not represent electrical power in a circuit? An electric bulb is rated V and W.

When it is operated on V, the power consumed will be �. Two conducting wires of the same material and of equal lengths and equal diameters are first connected in series and then parallel in a circuit across the same potential difference. The ratio of heat produced in series and parallel combinations would be �.

Solution: Let Rs be the equivalent resistance connected in series and Rp be the equivalent resistance connected in parallel. Let V be the potential difference. For same potential difference heat produced in given circuit will be given by following situation, where Hs and Hp is the heat produced in series and parallel circuit respectively. How is a voltmeter connected in the circuit to measure the potential difference between two points?

Answer: Voltmeter should be connected parallel to the two points, to measure the potential difference. A copper wire has diameter 0. How much does the resistance change if the diameter is doubled? Consider diameter of wire is doubled, therefore, the diameter of wire becomes 2 x 0. The values of current I flowing in a given resistor for the corresponding values of potential difference V across the resistor are given below � Plot a graph between V and I and calculate the resistance of that resistor.

When a 12 V battery is connected across an unknown resistor, there is a current of Ncert Solutions For Class 10th Science Chapter 3 2. Find the value of the resistance of the resistor. A battery of 9 V is connected in series with resistors of 0. This is not required resistance. Which is not the required resistance. Consider following figure. 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 5 A? What are the currents in the three cases? As circuit is in series combination, there is no division in the circuit and current of 2 A will flow through each and every component of the circuit. Also, voltage across each component in a parallel circuit is same.

Therefore, voltage across the parallel circuit will be 4V. Two lamps, one rated W at V, and the other 60W at V, are connected in parallel to electric mains supply. What current is drawn from the line if the supply voltage is V? Answer: Lamps are connected in parallel combination, therefore there is no division and same amount of voltage will pass through the circuit.

Which uses more energy, a W TV set in 1 hr, or a W toaster in 10 minutes? Calculate the rate at which heat is developed in the heater. Answer: Melting point of tungsten is very high. Therefore, tungsten is used exclusively for filament of electric lamps. Answer: Alloy has more resistivity than metals, also,heat producing ability of alloy is more as compared to metals. Therefore, electric heating devices like bread toasters and iron are made of alloy rather than pure metal.

Answer: Series arrangement is not use in domestic circuits. This is because in series circuit there is voltage division due to which components in the circuit receives small amount of voltage. Therefore, amount of current in the circuit decreases and device becomes hot.

Answer: Wires of copper and aluminium has low resistivity. Moreover copper and aluminium are good conductor of electricity. Thus, these are usually employed for electricity transmission. View Course Buy Course.

The ratio of heat produced in series and parallel combinations would be � a b c d Answer: c Solution: Let Rs be the equivalent resistance connected in series and Rp be the equivalent resistance connected in parallel.

I Ampere 0. Graph: Resistance can be calculated by taking the slope of the graph. Case ii When coils are used in series: Let R 2 be the equivalent resistance in series. Explain the following.
