A transistor is operated in common emitter configuration at V_(c)=2 V such that a change in the base current from 100 muA to 300 muA produces a change in the collector current from 10 mA to 20 mA . The current gain is

A coil is series with a 20muF capacitor across a 230V, 50Hz supply. The current taken by the circuit is 8A and the power consumed is 200W. Calculate the inductance of the coil if the current in the circuit is (a) leading (b) lagging

A triangular current carrying loop is placed in the X-Y plane with its vertices at P(0,(asqrt(3))/2),Q(-a/2,0) and R(a/2,0) . The loop carries a current l in the direction PtoQtoRtoP . Let the point S have the coordinates (0,(asqrt(3))/2) Choose the correct option(s):

In the circuit shown in figure : R = 10 Omega , L = (sqrt(3))/(10) H, R_(2) = 20 Omega and C = (sqrt(3))/(2) mF . Current in L - R_(1) circuit is I_(1) in C - R_(1) circuit is I_(2) and the main current is I At some instant current in L - R_(1) circuit is 10 A . At the same instant current in C - R_(2) branch will be

Two parallel wires carry currents of 20A and 40A in opposite directions. Another wire carrying a current antiparallel to 20A is placed midway between the two wires. The magnetic force on it will be
