Question

find the potential between a and b. Correct ans is option 3 that is 2.5 V​

Answer 1

Answer:

potential difference is 2.5V

Explanation:

as mentioned we need the current at point A and B

So,

we know according to OHM's law=

I=V/R= 5V-2V/5ohm+3ohm+10ohm= 3/18= 1/6A

then,

V= 2V+(3*1/6)

= 2+1/2

=4+1/2

=5/2

that is,

2.5 V
