Given information
It is given that at resistance, , voltmeter read
And, at resistance, , voltmeter read
Step-by-step explanation
Step 1.
The Ohm’s law tells that the ratio of voltage drop (V) and the current (I) passing through a resistance (R) is ideally constant which is equal to the value of that resistance itself, i.e.,
The current in the circuit at resistance, , voltmeter read
The current in the circuit at resistance, , voltmeter read
