The voltage supplying the current in the given circuit is _____.
Options
A. 2.5 V
B. 25 V
C. 250 V
D. 2.5 kV

Discuss

Correct Answer: 25 V

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.
