In Figure `E_1=12V` and `E_2=8V`
(a) What is the direction of the current in the resistor?
(b) Which battery is doing positive work?
(c) Which point, `A` or `B`, is at the higher potential?

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
a. `E_1gtE_2`
therefore, net curren is anti clockwise or from `B` to` A`.
b.current through `E_1` is normal. Hence,it is doing the positive work.
c. Current flows from `B` to `A`
`:. V_BgtV_A`
