hello friend ,i will help you with thsi
I will explain it
First of all we must find the least count of the ammeter and voltmeter. Least count is the smallest value that can be measured by the measuring instrument.
Least count = Range/Number of n divisions
/* Values for finding are inherited from the example images. */
Least count of ammeter = 1/50 = 0.02A Least count of voltmeter = 3/30 = 0.1V
The next part of the question asks us to find the current and potential difference/voltage passing through the resistor.
In this question,
Current = Value shown by ammeter × Least count = 15 × 0.02A = 0.3A
Voltage/Potential Difference = Value shown by voltmeter × Least count = 21 × 0.1V = 2.1V
hope my answer help ,pls mark as brainlist
