Ofss Interview Questions and Answers

An emf in a loop refers to the electromotive force generated in a closed circuit.

• An emf is generated when there is a change in magnetic flux through a loop of wire

• The emf can be calculated using Faraday's law of electromagnetic induction

• Emf can be induced in a loop by a changing magnetic field or by moving the loop through a magnetic field

• Emf is measured in volts

Charge on a capacitor is the amount of electric charge stored on its plates.

• The charge on a capacitor is directly proportional to the voltage across it and the capacitance of the capacitor.

• The formula for calculating the charge on a capacitor is Q = CV, where Q is the charge, C is the capacitance, and V is the voltage.

• The unit of charge on a capacitor is coulomb (C).
