The reason for which the resistance is given by
Answer to Problem 1ASA
The resistance of a circuit is the ratio between the voltage measured by the voltmeter and the current measured by the ammeter. So the resistance is given by
Explanation of Solution
The potential difference through an electric circuit is measured by using the voltmeter and the amount of flow of current through the circuit is measured by using the ammeter. The ammeter-voltmeter method is used to measure the resistance of the circuit.
Conclusion:
The Ohm’s law is used to measure, current, voltage, and resistance of a circuit if either two of them are given.
Write the expression for Ohm’s law.
