Question
Distinguish between an ammeter and a voltmeter.
| Ammeter | Voltmeter | ||
| i. | It measures current. | It measures the potential difference. | |
| ii. | It is connected in series. | It is connected in parallel. | |
| iii. | It is an MCG with low resistance. (Ideally zero) | It is an MCG with high resistance. (Ideally infinite) | |
| iv | The smaller the shunt, the greater will be the current measured. | The larger its resistance greater will be the potential difference measured. | |
| v. | Resistance of ammeter, R_(A)= (SG)/(S+G)=(G)/(n) | Resistance of voltmeter, R_(v)= G+X=Gn_(V) | |
