Answer #1

A series RC circuit consists of resistor with a resistance of 50.0 Ω and a capacitor with

capacitance value of 22 μF. The instantaneous voltage across the resistor (VR) is

given as

?? = 10 cos (2000??)

a) Derive an equation for the instantaneous current that flows in the circuit.

b) Calculate the reactance of the circuit

c) Derive an equation for the instantaneous voltage across the capacitor, Vc

d) Sketch a phasor diagram of the circuit.

e) Determine the equation for the instantaneous voltage of the ac source, Vs
