A series RC circuit has R = 5 Ω and C = 10 μF. The current in the circuit is 5 sin 20000t. The applied voltage is
Answer: Option
Explanation:
Z = R2 + XC2 = 50
V = 550 sin(20000 t - 45°)
V = 252 sin(20000 t - 45°)

Here the current leads to voltage, so it should be a positive phase shift, right?

Compare 5 sin20000t to a sin wt.
W=20000.
And please explain 45° phase shift.
W=20000.
And please explain 45° phase shift.

How we get 5ohms? Explain.

Get the reactance for the capacitor.
xc= 1/2wc = 5ohms.
w=2πF = 20000.
xc= 1/2wc = 5ohms.
w=2πF = 20000.
