What is a ametre?

Answer 1

Are we talking electricity here? And a meter for testing current flow?

An ammeter measures the amount of current (in amperes) in a closed, powered electrical circuit.

The formula, e=i*r (Voltage = current * resistance) when solved for i is

i=e/r

So if you have 120 volts flowing through a circuit that has a total resistance of 8 ohms, the current would equal 120 / 8 or 15 amperes.
