उत्तर
| 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, the greater will be the potential difference measured. |
| v. | Resistance of ammeter, RA = `"SG"/("S" + "G") = "G"/"n"` | Resistance of voltmeter, Rv = G + X = Gnv |
