A radio set operates at `6 V DC`. A transformer with 18 turns in the secondary coil is used to step down the input `220 V AC emf to 6 V AC emf`. This `AC emf` is then rectified by another circuit to give `6 V DC` which is fed to the radio. Find the number of turns in the primary.

A transformer converts 240 V AC to 60 V AC. The secondary has 75 turns. The number of turns in the primary are

A transformer with 20 turns in its secondary coil is used to step down the input 220 V ac emf. The output of the transformer is fed to a rectifier circuit which convents the ac input into dc output. The input and output of rectifier are as shown in Figure (there is no change in peak voltage). The rectifier output has an average emf of 8.98 volt. Calculate the number of turns in the primary coil of the transformer.

A setup transformer develops 440 V in secondary coil for an input of 200 V A.C Then the type of transformer is

A transformer converts 200 V ac into 2000 V ac. Calculate the number of turns in the secondary if the primary has 10 turns.

A transformer coverts 200 V ac into 2000 V ac. Calculate the number of turns in the secondary . If the primary has 10 turns.

The primary coil of a transformer has 100 turns and the secondary coil has 300 turns. If the peak value of the alternating emf applied to the primary coil 150v, what is the peakvalue of the alternating emf obtained across the secondary coil?
