Question

Complete the given statement . The voltage across each light bulb in a parallel circuit:

• A. is equal to the voltage of the battery
• B. is determined by the resistance of the bulb
• C. is determined by the current flowing through the bulb
• D. is equal to the sum of the voltages lost in each bulb
• E. is equal to the total current divided by the resistance of the bulb

Answer 1

The correct option is A is equal to the voltage of the battery

Let the resistance of each light bulb be $R_1$ and $R_2$.

From figure, $V_{AB}=V_{CD}=V$

Also $V_{AB}=I_1{R}_1$ and $V_{CD}=I_2{R}_2$

Thus option A is correct.
