Question

Please is there any formula to calculate what will be the corresponding value on voltmeter while verifying ohm's law without carrying out the experiment.
(Hint: battery to use is 3v, 2ohms resistor is connected to the voltmeter then to resistance box and key then to the battery.) Looking for any possible formula to calculate what will be the reading on voltmeter while varying the resistance in the resistance box.

Answer 1

At the recommended resistance values, there will still be a small amount of measurement ... Build a one-battery, one-resistor circuit. ... Be sure to check out our Ohm's Law Calculator
