QUESTION [3]
A no-load and short-circuit test should be conducted on a 220V/110V, 280VA transformer.
a. Draw the circuit diagram for the no-load test and include all measurements that should
be made. Also write down the maximum voltage that you should apply to the primary
winding and estimate the current drawn from the supply.
