If the current in the resistor R in diagram above is 0.05A, calculate the p.d. across the inductor.
Attached Figure / Diagram
A
2.5V
B
25.0V
C
49.0V
D
50.0V
E
250.0V
Verified Correct Answer: A.
Physical Principles & Numerical Solution
V= i \times \(_l\)
X\(_l\) = inductive reactance → 50
I = current → 0.05A
V = 0.05 \times 50
V = 2.5volt
