Q Define: self inductance.
The coefficient of self induction of a coil is numerically equivalent to the opposing emf induced in the coil when the rate of change of current through the coil is unity. The unit of a self inductance is henry (H).
The rate of modification of thermo emf with the change in the temperature of the hot junction is known as thermoelectric power.
