A.C can be measure withthe help of:
Correct answer: C. Hot wire ammeter
- A. Ammeter (D.C)
- B. Moving coil galvanometer
- C. Hot wire ammeter
- D. All of the above
Explanation
Hot wire ammeter, refers to a device specifically designed to measure alternating current (AC) accurately by passing the current through a fine wire, which heats up proportionally to the current flow. This method allows for precise measurement of AC.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
