The voltage supplying the current in the given circuit is _____.

2.5 V
25 V
250 V
2.5 kV
Answer: Option
Explanation:

V = IR

= 250 x 10^-6 x 100 x 10^3

= 250 x 100 x 10^(-6+3)

= 250 x 100 x 10^-3

= 25 x 1000 x 10^-3

= 25 x 10^3 x 10^-3

= 25 x 10^0

= 25 x 1 [Anything power 0 is 1]

= 25 volts.

Simply V = IR.
= (250/1000000A) * (100*1000ohm),
= 250/1000000 * 100000,
= 25volt.
