Answer 1

Answer:

( 1 ). Potential difference is measured in volts by using a voltmeter placed in parallel across a component.

( 2 ). Copper is a good conductor and plastic is an insulator.

( 3 ). Current is measured in amperes using an ammeter placed in series in a circuit.

( 4 ). Resistance is measured in Ohms.

( 5 ). The resistance of a wire increases as the cross sectional area resistance decreases.
