Current time graph capacitor
WebA capacitor is discharged through a 10 MΩ resistor and it is found that the time constant is 200 s. Calculate the value of the capacitor. RC= 200 Therefore C = 200/10 x 10 6 = 20 μF. 3. Calculate the time for the potential across a 100 ΨF capacitor to fall to 80 per cent of its original value if it is discharged through a 20 kΩ resistor. WebCharging Capacitors What happens to current as time passes? As explained above, current falls away as it becomes less attractive for electrons to move to the plate from the cell. Note: The area under the …
