In the circuit shown, two identical 1.5 V batteries (with the positive or high potential ends colored orange) are connected to three identical bulbs, A, B, and C. The current in bulb A is *I*_{0}.

A. What is the current in bulb B? Express your answer as a number multiplied by *I*_{0}, and enter that number here:

_____ × *I*_{0}

B. What is the current in bulb C? Express your answer as a number multiplied by *I*_{0}, and enter that number here:

_____× *I*_{0}

Suppose that each of the bulbs has a resistance of 50 Ω.

C. Calculate *I*_{0}, the current in bulb A.*I*_{0} = _______ amps

Step 1

Given:

Current in bulb A = I_{ο}

e.m.f = 1.5 V

resistance of each bulb = 50 Ω

Step 2

Current in the bulb B can be determined as:

Since the bulb A and B are of same resistance and connected in parallel. Therefore, the current in both the bulb will also be same.

Current in the bulb B is also I_{ο}

Step 3

Current in the bulb C:

From figure, current flowing in b...
