The time required to fully charge a 1 µ(micro)F capacitor in series with a 100k ohm resistor is
- 100 seconds.
- 100 milliseconds.
- 500 milliseconds.
hanozd asking:
the ans should be 100 millisec. T=RC.

Hello.
You are wrong.
RC is not a time of full charge, it is time constant.
So, time constant is 100 ms. Time-constant is time to reach 63.2% of full charge. Time to fully charge = 5 * TC
So, time to full charge is 500 ms.
