What is regenerative braking
Explain the term regenerative braking?

Whenever the supply is not available for the running motor, it will still continue running because of inertia. To stop it rapidly we need to place the load across armature winding and motor must have managed continuous field supply so that back e.m.f voltage is formed to apply across resistor and because of load motor stops rapidly. Such type of breaking is said to be Regenerative Breaking.
A step-down transformer that operating from a 50Hz mains supply of 220 Volt rms, is used to give a decrease voltage to a secondary power supply. The final delivers 400 Watt of power to a load consisting of an equivalent resistance of 10?. The transformer should have a
