When there is current during only one-half of the A.C. input cycle in a ciruit, then it is called

The mean value of AC current in half cycle and in full cycle is

The first half of menstrual cycle is called:

A change of 0.04 V takes place between the base and the emitter when an input signal is connected to the CE transistor amplifier. As a result, 20 mu A change takes place in the base current and a change of 2 mA takes place in the collector current. Find the input resistance and A.C. current gain

A change of 0.04 V takes place between the base and the emitter when an input signal is connected to the CE transistor amplifier. As a result, 20 muA change takes place in the base current and a change of 2 mA takes place in the collector current. Find the input resistance and A.C. current gain.

When there is resonance in an a.c. circuit containing L,C and R, the current

An L-C-R series circuit with R=100Omega is connected to a 200V , 50Hz a.c. source .When only the capacitance is removed, the voltage leads the current by 60^(@) and when only the inductance is removed, the current leads the voltage by 60^(@) . The current in the circuit is

An L-C-R series circuit with R = 100 Omega is connected to a 200 V, 50 Hz A.C. source when only the capacitance is removed, the current lags the voltage by 60^@ . When only the inductance is removed, the current leads the voltage by 60^@ . Find the current in the circuit.
