How to take reading of ammeter and voltmeter

WebMay 25, 2024 · Therefore, voltmeter reading, V = VR + Va. Where, V R = IR, V a = IR a. V = IR + IRa. V = I (R + Ra) Therefore, measured value of resistance, From the above equation, the measured value is not equal to the exact value or the true value of the unknown resistance. This is because of the inherent resistance of the ammeter. WebApr 11, 2024 · A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current. At the heart of most analog meters is …
