Would adding another capacitor in parallel to an RC circuit increase, decrease, or not change its time constant?This problem involves analyzing an RC circuit. See the circuit diagram below. Switch closes at t = 0 s. А. When the switch closes at t = 0, the capacitor will begin to charge. What is AVc a very long time after the switch has closed?
