Question

what will be the p.d across the combination of applied potential 6 volt

Answer 1

The potential difference would be same as potential applied and that is 6 Volt.


Thank you.

Answer 2

8.4V is the answer

Applying Kirchoff's Voltage Law in the loop,

$2I − 6 + 12 + 3I = 0$

$⟹ 5I = −6$

$⟹ I = −1.2A$

P.D across 6V battery =

$6 − 2I = 6 + 2.4 = 8.4V$

8.4 V is the answer
