An ammeter and a voltmeter of suitable ranges are to be used to measure the current and voltage of an electric lamp. If mistakes were made and meters interchanged, what will happen? When we connect an ammeter in parallel, as we know that current always follows low resistance path, maximum amount of current will flow through the ammeter which in turn will burn the fuse or can damage the ammeter. Connecting ammeter like this, is like connecting a wire from positive terminal to negative terminal where short circuit will happen. A short circuit is when there is a low resistance connection between two conductors that are supplying electrical power to a circuit. This would generate an excess of voltage streaming and cause excessive flow of current in the power source. The electricity will flow through a 'short' route and cause a short circuit. If the voltmeter is connected in parallel,it will not able to read anything. Resistance of an ideal voltmeter is infinity. If a voltmeter is connected in series in a circuit it will lead to open circuit condition in the circuit and no current flows through the circuit and voltmeter will show zero reading as current through the meter is also zero.
