a) Draw a schematic time dependence of the voltage across a capacitor when the initially fully discharged capacitor is being charged by a DC voltage source. The capacitor of capacitance C is in series with a resistor with resistance R. Indicate schematically the value of the voltage when the charging time is 6RC. b) Draw a schematic time dependence of the voltage across a capacitor when the fully charged capacitor is being discharged. The capacitor with capacitance C is in series with a resistor of resistance R. Indicate schematically the value of the voltage when the discharging time is 6RC.
8. a) Is Kirchhoff’s voltage law applied to AC circuits (yes or no)? b) Is Kirchhoff’s current law applied to AC circuits (yes or no)?
