Question

to verify the ohms law and state the effect of mutual change of ammeter and voltmeter ​

Answer 1

Explanation: Ohm’s Law can be verified is we manage to show that for a given conductor (piece of wire) the ratio V:I is constant. Resistance of the conductor is a constant for a known temperature range. To verify this law you can set up a circuit with resistors of fixed values, a variable voltage source, a voltmeter and an ammeter
