20.0 Ω resistor and a 2.50 μF capacitor are connected in parallel with signal generator. The signal generator produces a sinusoidal voltage with an amplitude 3.00 V at a frequency of f=2.48e3 Hz What is the maximum current provided by the power supply?'

0.15A

Explanation:

The parameters given are;

R=20.0 Ω

C = 2.50 μF

V = 3.00 V

f = 2.48*10^-3 Hz

Xc = 1/2πFc

Xc = 1/2*3.142 * 2.48*10^-3 * 2.5 * 10^-6

Xc = 25666824.1

Z = 1/√ (1/R) ^2 + (1/Xc) ^2

Z = 1/√[ (1/20) ^2 + (1/25666824.1) ^2]

Z = 1/√ (2.5*10^-3) + (1.5*10^-15)

Z = 20 Ω

But

V=IZ

Where;

V = voltage

I = current

Z = impedance

I = V/Z

I = 3.00/20

I = 0.15A
