A solenoid has 200 turns and the magnetic flux linked with it changes from 0 Wb to 0.4 Wb in 0.5 seconds. Calculate the induced EMF.
💡 Hint: Use the formula and ensure you find the rate of change of flux first.
If a transformer has a primary winding of 300 turns and is designed to step down the voltage to 50 V in the secondary with a supply of 150 V, calculate the number of turns in the secondary winding.
💡 Hint: Make sure to rearrange the ratio correctly.
