potential difference across 4 Ω Ω resistance is equal to the potential difference across 6 Ω Ω resistance

Current in wire AB is zero

Text Solution

The correct answer is:

CHECK THE SOLUTION.

(a, c)

4 Ω Ω and 6 Ω Ω resistance are short circuited. Therefore, no current will flow through these two resistances. Current passing through the battery is

i = = 10 A

This is also the current passing in wire AB from B to A.

Power supplied by the battery P = E i

(20) (10)

= 200 W

Potential difference across 4 Ω Ω resistance

= potential difference across 6 Ω Ω resistance = 0
