A CB amplifier has a = 0.98 and RL = 600 Ω. If IE = 3.5 mA, the current gain is
-
Assertion (A): In an RC coupled amplifier the junction capacitances can be neglected at low frequencies but not at high frequencies
Reason (R): Capacitive reactance is inversely proportional to frequency.

In the circuit of figure both diodes are ideal. If v1 = 10 V and v2 = 10 V which diode will conduct?
-
In the circuit of the given figure, assume that the diodes are ideal and the meter is an average indicating ammeter, the ammeter will read
