Physics for IGCSE & O level - Magnets And Currents (Section 1 - No. 39)
What is the formula for calculating the voltage across the input coil?
input voltage/output voltage = turns on input coil/ turns on output coil
input voltage/output voltage = turns on output coil/ turns on input coil
input voltage = output voltage
input voltage * output voltage = turns on input coil / turns on output coil
