The no-load speed of a 230 V separately excited dc motor is 1400 rpm. The armature resistance drop and the brush drop are neglected. The field current is kept constant at ratedvalue. The torque of the motor in Nm for an armature current of 8 A is ____________.
Question 7
An air-cored solenoid of 250 turns has a cross-sectional area A = 80 cm2 and length l = 100 cm. The value of its inductance is
Question 8
The self-capacitance of a coil is measured by the resonating capacitor. The measurement gives the value of tuning capacitor as C1 = 460 pF at a frequency.
f1 = 2 MHz. The second measurement at
f2 = 4 MHz yields a new value of tuning capacitor, C2 = 100 pf. The distributed capacitance Cd will be
f1 = 2 MHz. The second measurement at
f2 = 4 MHz yields a new value of tuning capacitor, C2 = 100 pf. The distributed capacitance Cd will be
Question 9
Consider the following circuit.
The maximum current output of or into the output of the driving gate G1 is
