In the experiment of calibration of voltmeter, a standard
cell of emf `1.1 V` is balanced against `440 cm` of
potentiometer wire. The potentail difference across the
ends of a resistance is found to balance aginst `220 cm` of the wire. The corresponding reading of the voltmeter is `0.5 V`. Find theerror in the reading of voltmeter.

To solve the problem of finding the error in the reading of the voltmeter, we can follow these steps: ### Step 1: Calculate the Potential Gradient (K) The potential gradient (K) can be calculated using the formula: \[ K = \frac{V}{L} \] where \( V \) is the EMF of the standard cell and \( L \) is the length of the potentiometer wire. Given: ...
