If you want to learn more about the nature and properties of matter and energy or you're simply preparing for a Physics exam, these Physics past questions and answers are ideal for you.
If the current in the resistor R in diagram above is 0.05A, calculate the p.d. across the inductor.
2.5V
25.0V
49.0V
50.0V
250.0V
Correct answer is A
V= i × l
Xl = inductive reactance → 50
I = current → 0.05A
V = 0.05 × 50
V = 2.5volt
Calculate the inductive reactance of the circuit shown above.
50.00
5.00
0.50
0.05
0.02
Correct answer is A
