State the condition in which the terminal voltage of a secondary cell is equal to emf.

A step up transformer converts a low input voltage into a high output voltage. Does it violate law of conservation of energy? Explain.

In the circuit shown in Fig. EP. 14.7, if the diode forward voltage drop is 0.3 V, the voltage differnece between A and B is

What is knee voltage?

Define Zener voltage.

Why the output voltage is out of phase with the input voltage ina common emitter transistor amplifier?

A crystal diode having internal resistance 200Omega is used as a half rectifier. If the applied voltage is V=50 sin omegat volt and load resistance is 800Omega , find maximum output current

In a p-n junction diode, the current I can be expressed as I = I_0 exp ((eV)/(2k_BT)) where I_0 is called the reverse saturation current, V is the voltage across the diode and is positive for forward bias and negative for reverse bias, and I is the current through the diode, k_B is th Boltzmann constant (8.6xx 10^-5 (eV)/K) and T is the absolute temperature. If for a given diode I_0 = 5 xx 10^-12 A and T = 300 K, then - What is the dynamic resistance when the voltage is increased to 0.7 V from 0.6 V?
