But charge starts to build up on the capacitor, so some voltage is dropped across the capacitor now. With less voltage being dropped across the resistor, the current drops off. With less current, the rate at which charge goes onto the capacitor decreases. The charge continues to build up, but the rate of that build up continues to decrease.
The voltage drop across a capacitor is proportional to its charge, and it is uncharged at the beginning; whereas the voltage across the resistor is proportinal to the current and there is a current at the start. But charge starts to build up on the capacitor, so some voltage is dropped across the capacitor now.
Likely because the mistake could have caused some discharge of one or more of the capacitors, affecting their voltage. So you discharge all the capacitors and start over to make sure the measurements are accurate. Did the instructor ask you to calculate what the expected cap voltages should be?
When a voltage is placed across the capacitor the potential cannot rise to the applied value instantaneously. As the charge on the terminals builds up to its final value it tends to repel the addition of further charge. (b) the resistance of the circuit through which it is being charged or is discharging.
Large capacitors can store enough energy to inflict injuries, so they must be appropriately discharged. When a capacitor is disconnected, it retains its accumulated voltage (and current) across the previously connected terminals, which is notably dangerous.
Capacitors oppose changes of voltage. If you have a positive voltage X across the plates, and apply voltage Y: the capacitor will charge if Y > X and discharge if X > Y. calculate a capacitance value to discharge with certain voltage and current values over a specific amount of time
