Question 290Electricity & Electronics - QMED
70% to passWhat is an ammeter used to measure?
Atotal or partial circuit resistance
Bcircuit continuity
Cthe voltage between two points in a circuit
Dcurrent flow in a circuit
AI Explanation
The correct answer is D) current flow in a circuit. An ammeter is a device used to measure the amount of current (flow of electric charge) passing through a particular point in an electrical circuit. It is connected in series with the component or circuit being measured, so that all the current flowing through the circuit must also flow through the ammeter. This allows the ammeter to directly measure the current at that point in the circuit. The other answer choices are incorrect because they measure different electrical properties - A) resistance, B) continuity, and C) voltage, rather than current flow.
