any circuit
1)What is the phase difference between voltage and current in a circuit including only a capacitor and an AC source? 2)Does current lag or lead a voltage?
1)1800
2) electric current leads voltage
electric current lags the voltage by 900
Phase difference =1800
the voltage leads, the current lags
Phase difference =900
Electric current leads, the voltage lags
