A 24-slot, 2-pole, lap-would dc machine has 18 turns per coil. The average flux density per pole is 1 Tesla. The effective length of the machine is 20 cm and the radius of the armature is 10 cm. The magnetic poles cover 80% of the armature periphery. For armature angular velocity (ω_m) of 183.2 rad/se, the induced emf in the armature winding is nearly

A single phase full converter RL load is operating as a firing angle of 30° and an extinction angle of 200°. This angle for which free-wheeling diode operate in one cycle of input supply will be.

1-ϕ dual converter has 1 unit working with firing angle of 60° and the other unit works as _______ at an angle of _______.

Amplitude modulation is used for broadcasting because

Find V_o if 3 mV, 2 kHz sinusoidal Signal is applied at input terminal. If R = 5 kΩ & C = 5 μF

The Fourier transform of signal te^–tu(t) is

A flip flop is also called as

A shunt reactor is operating for 0.98 times of its rated voltage and 0.96 times of its rated frequency. The reactive power absorbed by reactor ________ MVAr, if rating of shunt reactor is 100 MVAr.

Which of the following bridge is used for the measurement of frequency?

Which of the following is incorrectly method?

In the circuit shown below, the transistor parameters are V_Th = 0.5 V and μ_nC_ox = 200 μA/V² and it operates on the verge of saturation, then W/L is

The output ripple voltage in a buck dc-dc converter is calculated from:

For induction motor, delta connected develops:

(i) Full load Torque = 40 Nm

(ii) Starting Torque = 80 Nm

Now, the motor changed to star connected, its starting torque developed in Nm, (Consider same supply voltage).
