Physics-Electric circuits

What type of energy is found in batteries?

Chemical potential energy

Definition of EMF

The maximum energy provided by a battery per unit charge passing through it

What does the emf reading on a battery indicate?

It indicates the total amount of energy that can be supplied to the electrons

What is the law of charge quantisation?

All charges in the universe consists of an integer multiple of the charge of one electron

Potential difference

The potential difference across the ends of a conductor as the energy transferred per unit of electric charge flowing through it

Electric current

The rate at which charge flows

Ohms law

The potential difference across a conductor is directly proportional to the current in the conductor at a constant temperature

Resistance

The ratio of potential difference across a resistor to the current in the resistor

Coulomb

One coulomb is defined as the charge transferred in a conductor in one second if the current is 1 ampere
