The output of a step-down transformer is measured to be 24 V when connected to a 12 watt light bulb. The value of the peak current
The Transformer Transformer is a device, which is used to increase or decrease the alternating voltage. The transformers are of the following types (i) Step-up transformer (ii) Step-down transformerTransformer is based upon the principle of mutual induction. It consists of two coils, primary coil `(p)` and secondary coil `(s)`, insulated from each other wounded on soft iron core.Often the primary coil is the input coil and secondary coil is the output coil. These soft iron cores are laminated to minimise eddy current loss.A transformer has 150 turns in its primary and 1000 in secondary. If the primary is connected to
