Chapter 7, Problem 24RQ

Two transformers rated at 100 kVA each are connected in an open-delta connection. What is the total output power that can be supplied by this bank?

A 10 kVA transformer has a primary voltage rating of 240 volts and a secondary voltage rating of 480 volts. The transformer is connected to a circuit protected by a 100 ampere circuit breaker. The secondary is protected by a 25-ampere fuse. Does the primary require separate overcurrent protection?

Assume that a primary current of 75 amperes flows through the windings of the transformer in question 4. How much current will flow in the secondary winding?

The alternating current produced by the AC generator is rectified into DC, or direct current, through the use of. transistors electromagnetic relays diodes capacitors

If the secondary of the transformer in question 5 supplies a current of 9.6 amperes to a load, what is the primary current? (Disregard excitation current.)

What two factors determine the polarity of the output voltage produced by the Hall generator?

what is unit impulse response?

1) What is the name for 1, 2, 5 and 6 respectively? 2) What is the function of this circuit? Describe its working principle briefly.
