Question 5

The normal current in a power line is 100 A. If a short-circuit fault occurs on the line, then one can expect the short-circuit current to be

Question 6

One of the speeds of a 2-speed squirrel cage induction motor is

(lower speed). The other speed will be……………

Question 7

An amplifier feeding a resistive load of 1kΩ has a voltage gain of 40 dB. If the input signal is 10 mV, find output voltage.

Question 8

In voltage divider circuit as shown, if load B is connected across terminal points 1 and 2 in the circuit shown, then what will be the effect in the overall circuit?

Question 9

The current through a branch in a linear circuit is 2A when the input source voltage is 10V. If the voltage is reduced to 1V and the polarity is reversed, the current through the branch is

Question 10

A 50 Hz, 11 kV, 3-phase alternator with earthed neutral has a reactance of 5 ohms per phase and is connected to a bus-bar through a circuit breaker. The distributed capacitance upto circuit breaker between phase and neutral is 0.01, the average rate of rise of re-striking voltage upto the first peak is
