WHY DO WE CONNECT AMMETER IN SERIES AND VOLTMETER IN PARALLEL? |
| The Voltmeter is used to measure the electrical potential difference between two points... so it's no use to connect it in Series , because the electrical potential difference between two points at the same line is zero ==> the readings will always be zero. The Ammeter is used to measure the electric current in a circuit... so it's no use to connect it in Parallel , because you want to know the current flowing in this wire. note the internal Resistance of the Ammeter is very little and very high for the Voltmeter --> so they will not affect the circuit. |
