Explanation:
R = V ÷ I Question
What is the resistance of the lamp? To calculate the resistance of an electrical component, an ammeter is used to measure the current and a voltmeter to measure the potential difference. The resistance can then be calculated using Ohm's Law.

One statement of Ohm's law gives the relationship between current I, voltage V, and resistance R in a simple circuit to be I=VR I = V R . Resistance has units of ohms (Ω), related to volts and amperes by 1 Ω = 1 V/A.
