我想問下呢一個CR circuit 入面...要charge up 一個capacitor..咁個battery input 既energy 係幾多呀?...照計就應該會...input = energy dissipated in the resistance of the circuit + energy stored in cap.
energy stored in cap. =1/2 CV^2
咁energy dissipated in the resistance of the circuit 點計??
唔該...
power input for charge up a capacitor
