What is the source voltage applied across a loop containing a resistor of 500 ohm and capacitor of 10 microfarads in series when a current of 0.02 ampere flows across the circuit? Given that the voltage drop across capacitor is 2 Volts.

Given : Voltage drop across capacitor = 2 Volts Current in loop = 0.02 ampere Resistance = 500 ohm Capacitance=10 microfarads Drop across resistor=500*0.02 Drop across resistor=10 Volts Source voltage (Total Voltage) = Drop across resistor + Drop across resistor Source voltage = 10 Volts + 2 Volts Source voltage=12 Volts.
