Part A Charging of RC Circuit 1) Construct a RC circuit (series) with a capacitor, a resistor, a battery, two switches, and appropriate meters that will enable you to make measurements of the parameters for charging up the capacitor. The placement of the switches allows you to measure both charging and discharging of the RC circuit. See diagram below: 2) Choose a combination of Rand C that will give you a time constant(T) of 20 seconds. T=R*C 20= 100* C=0.2F 3) Set the...
