A transformer has 400 turns on the primary and 100 turns on the secondary. If 120 volts AC are applied across the primarywindings, calculate the voltage induced in the secondary.

The diagram below represents a voltage step-down transformer with 1000 turns on the primary coil and 100 turns on the secondary. The primary is connected to a 10 V AC supply and a 10 Ω resistor is connected across the secondary. You may assume that the transformer is ideal, i.e. there are no flux or other losses. The current flowing in the primary circuit is to one decimal place in mA:

If a transformer have turn ratio 5, frequency 50 Hz, root mean square value of potential difference on primary winding is 100 volts and the resistance of the secondary winding is 500  then the peak value of voltage in secondary winding will be (the efficiency of the transformer is hundred percent)-

2.0 A in the 100-turn primary of a transformer causes 14 A to flow in the secondary. How many turns are in the secondary?Group of answer choices700144114
