The current in a conductor and the potential difference across its ends are measured by an ammeter and a voltmeter.The meters draw negligible current.The ammeter is accurate but the vlotmeter has a zero error(that is ,it does not read zero when no potential difference is applied).Calculate the zero error if the readings for two different conditions are 1.75A, 14.4Vand 2.75a, 22.4V.

To solve the problem of calculating the zero error of the voltmeter, we will follow these steps: ### Step 1: Understand the relationship between current, voltage, and resistance According to Ohm's Law, the relationship between current (I), voltage (V), and resistance (R) is given by: \[ V = I \cdot R \] In this case, we have two different conditions with different currents and voltages. ### Step 2: Set up the equations for both conditions ...
