How can you make a galvanometer sensitive

WebA potentiometer is an instrument for measuring voltage or 'potential difference' by comparison of an unknown voltage with a known reference voltage. If a sensitive indicating instrument is used, very little current is drawn from the source of the unknown voltage. Since the reference voltage can be produced from an accurately calibrated voltage ... Web30 de dez. de 2024 · From principle V = I x R. Now we know the value I = current of meter DC1mA. But we do not know the resistance (R) Best way is measured directly is 234 ohms only. Thus; V = 234 ohms x 1mA = 234mV or 0.234V. If we take it to measure the voltage 10V, the our galvanometer certainly damage as Figure 4.
