Question

How are voltmeter and ammeter joined on passing current in a resistor?

Hint:

Always connect an ammeter in series and a voltmeter in parallel to measure current and voltage, respectively.

Answer 1

1. Ammeter is always connected in series with the resistor to measure the current flowing through it.
2. Voltmeter is connected in parallel across the resistor to measure the potential difference.
This is because an ammeter has low resistance, allowing current to pass through, whereas a voltmeter has high resistance, preventing it from altering circuit behavior.
