Describe the change in current when an ammeter is inserted into a circuit


When an ammeter is inserted into a circuit, the current to be measured is changed by the introduction of the ammeter. It is essential that the change in current thus caused shall be a very small fraction of the current itself; i.e., the resistance of the ammeter must be a small fraction of the total resistance of the circuit.
