Question

An ammeter is always connected is series across a circuit? What will happen if it is connected in parallel?

Answer 1

Dear Student,

An ammeter is connected in series with the circuit because the purpose of the ammeter is to measure the current through the circuit. Since the ammeter is a low resistance device, connecting it in parallel with the circuit would cause a short circuit, damaging the ammeter and/or the circuit. It should be connected in series, so that maximum current can pass through it, for accurate measurement of current.
