ECE :: Electromagnetic Induction
- Current changing from 8 A to 12 A in one second induced 20 volts in a coil. The value of inductance is
- A coil induces 350 mV when the current changes at the rate of 1 A/s. The value of inductance is
- The direction of induced e.m.f. can be found by
- In an iron cored coil the iron core is removed so that the coil becomes an air cored coil. The inductance of the coil will
- Higher the self-inductance of a coil,
- The inductance of a coil will increase under all the following conditions except
- The self-inductance of the coil may be defined as equal to the e.m.f. induced in volts when the current in the circuit changes at the rate of unit Weber turns.
- As per Faraday's laws of electromagnetic induction, an e.m.f. is induced in a conductor whenever it
- The coefficient of coupling between two air core coils depends on
- Air-core coils are practically free from
