RC Circuit • Important points to consider: • common log: 100 = 102 ; so, log10 100 = 2 • natural log: 20 = e3 ; so ln 20 = 3 • Vo the supply voltage • RC characteristic time constant The Problem: A series circuit consists of R = 50.0 M , C = 6.00 F, and V = 10.0 V DC. The capacitor is initially discharged. When the power supply is turned on (t = 0), how long (in seconds) will it take for the capacitor to charge to 8.00 V?
For charging: Solve for t:
