A forward-biased silicon diode has a voltage drop of 0.64 V at negligible current. When the current is 1 A and it dissipates 1 W, the ON resistance of the diode is:
In the circuit shown, the ideality factor \( \eta \) of the diode is unity and the voltage drop across it is 0.7 V. The dynamic resistance of the diode at room temperature is approximately:
the ideality factor η of the diode is unity and the voltage drop across
