Which instrument is used to measure the electric charge in coulombs?
hard Q10 of 15
Step-by-Step Solution
Step 1: Understand the physical quantity
The question asks for the instrument that measures electric charge in coulombs.Step 2: Recall instrument functions
Electrometer measures electric charge or potential. Galvanometer measures small currents, Voltmeter measures voltage, Ammeter measures current.Step 3: Analyze why other options are incorrect
Galvanometer and ammeter measure current, not charge. Voltmeter measures potential difference, not charge.Final Answer:
Electrometer → Option DQuick Check:
Electric charge measurement = Electrometer ✅
Quick Trick: Electrometer measures electric charge in coulombs.
Common Mistakes:
- Confusing galvanometer or ammeter with electrometer.
