The resistance of each bulb in a given series circuit.
Answer to Problem 3PP
The resistance of each bulb in the circuit is
Explanation of Solution
Given:
A series of ten identical bulbs with equal resistance values connected to a 117-V outlet and current through the circuit is 0.06 A.
Formula used:
Given the current flowing through a circuit and supply voltage, the total resistance can be calculated using the Ohm’s law as,
Also, the equivalent resistance of the series resistors is the sum of individual resistance values.
Calculation:
For the series circuit with a voltage of 110 V and current 0.06 A, total resistance of the light circuit can be calculated by using the relation in (1) as
Now, since the circuit consists of ten identical bulbs in series the above resistance value, the resistance of each bulb can be calculated using (2) as,
Conclusion:
Therefore, the resistance of each bulb is
