Challenge Circuit 5

capacitor charging Circuit

Capacitors charge when DC voltage is applied across them. By connecting a resistor in series with a capacitor we can control the amount of current that goes through and hence the time it takes to charge it.

For the given circuit, if the values are:

  • C = 1000 uF
  • R = 4.7k ohms
  • Supply voltage = 12V

Calculate the following
