What is the charge on the capacitor being charged up by a 25 V battery

Click For Summary
SUMMARY

The charge on a capacitor in an RC circuit charged by a 25 V battery can be calculated using the formula Q = C * V. After two time constants, the charge on a 15 µF capacitor approaches approximately 86.5% of the maximum charge, which is 25 V. Therefore, the charge Q can be determined as Q = 15 µF * 25 V = 375 µC.

A capacitor in a RC circuit is initially uncharged. What is the charge on the capacitor being charged up by a 25 V battery for a period of two time constants of the RC circuit? (C = 15 µF, R = unknown)


How do I find Q?
