1. Battery is a source of energy for a circuit, whereas capacitor is a passive element, which draws energy from the circuit, store and release it. 2. Usually battery is a DC component, whereas capacitor is mostly used for AC applications. It is used to block DC components in circuits.
what is the difference btween BJT , JFET,Mosfet. difference between jfet and mosfet A BJT is a bipolar transistor in the sense that there are two types of charge carriers in them. In npn trnsistor the primary carrier in the hole and in pnp the electron. In JFET there is only one type of carrier. In n-channel case the carrier is elctron and in p-channel hole.
