Class 10 Physics Chapter 15 Numerical Problems Notes

  • A transformer is needed to convert a mains 240 V supply into a 12 V supply. If there are 2000 turns on the primary coil, find the number of turns on the secondary coil.
  • A step-up transformer has a turn ratio of 1: 100. An alternating supply of 20 V is connected across the primary coil. What is the secondary voltage?
  • A step-down transformer has a turn ratio of 100: 1. An AC voltage of 170 V is applied to the primary. If the current in the primary is 1.0 mA, what is the current in the secondary?
  • A transformer, designed to convert the voltage from 240 V a.c mains to 12 V, has 4000 turns on the primary coil. How many turns should be on the secondary coil? If the transformer were 100% efficient, what current would flow through the primary coil when the current in the secondary coil was 0.4 A?
  • A power station generates 500 MW of electrical power fed to a transmission line. What current would flow in the transmission line, if the input voltage is 250 kV?
