Question

4. Consider a driven RC circuit with Voltage amplitude of 5 V (i.e. Peak to Peak Voltage of 10V)

and frequency f. R=100 and C =1μF

a) Come up with an expression for the maximum current

b) Come up with an expression for the phase between the current and the voltage

c) does the voltage lead or lag the current?

d) what is the peak current for f= 60Hz and f= 1kHz

e) For which frequency in d) is the peak voltage across the resistor greatest
