Answer: Ammeters have a very low resistance and are placed in series with a resistor.

Ammeters have a very low resistance so as to not significantly alter the total resistance of a circuit.

Voltmeters have a relatively high resistance and are placed in parallel with a resistor.

Explanation: An ammeter is a device which used to measure current in a circuit. Thus, it is placed in series with the other components of the circuit. In series, the current remains same throughout the circuit and depends on the net resistance of the circuit.

This, the ammeter must have very low resistance so that it doesn't alter the net resistance of the circuit.

A voltmeter is a device which is used to measure potential drop across a component in a circuit. Thus, it is placed in parallel combination to to the component. The resistance of a voltmeter must be high so that no current flows through it and alters the potential drop across the component.
