Explanation:
Ammeter —> The main principle of ammeter is that it must have a very low resistance and also inductive reactance
Voltmeter—> The main principle of voltmeter is that it must be connected in parallel in which we want to measure the voltage. Parallel connection is used because a voltmeter is constructed in such a way that it has a very high value of resistance.
