Set up the following RC circuit and obtain the graphs of voltage across the capacitor and the current on the branch where the capacitor is placed during Charging and Discharging of the capacitor and compare the time constants of two events. (You may use different ways of switching in your circuit)

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
