- Question
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
- Correct Answer
- 25 V
ExplanationV = 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.
