Ammeter -> It is a device used to calculate electric current flowing through a circuit. It is connected in series.
Voltmeter -> It is a device used to calculate the potential difference across a conductor. It is connected in parallel to the conductor.
Resistance -> It is defined as the ratio of potential difference across the conductor to the electric current flowing through it.
or
It is the property of a conductor to resist the flow of charges.
