Compensation electromotive force (emf) refers to an additional voltage introduced in a circuit to counteract the effects of unwanted voltages, such as those caused by temperature variations or load changes. It is often used in measuring instruments, like galvanometers, to ensure accurate readings by offsetting errors. This technique helps maintain the precision of measurements and enhances the instrument's performance under varying conditions.

How are emf measured?
emf in volts
Does motional emf call induced emf?
yes indused emf is also called motional emf. If an open coil is subjected to a variable magnetic field, at the ends of the coil a potential difference is induced which is called induced emf. If a coil is connected to an emf source and switched on, the rising current will produced an variable magnetic field which in turn produces an emf. It is called back emf.

Why emf of battery driving potentiometer is greater than emf of the cell to be measured?
Bcoz the emf which is to be measured is less than emf of driving cell....
