Watt hour meter measures
Text Solution
Verified by ExpertsThe correct answer is:
B
Step 1: Understand the function of a watt-hour meter.
A watt-hour meter, commonly used in households and industries, measures the amount of electrical energy consumed over time. The unit of measurement is watt-hours (Wh), which signifies the energy consumed when one watt of power is used for one hour.
Step 2: Analyze the options:
A watt-hour meter, commonly used in households and industries, measures the amount of electrical energy consumed over time. The unit of measurement is watt-hours (Wh), which signifies the energy consumed when one watt of power is used for one hour.
Step 2: Analyze the options:
- Option A: Current - This is measured in Amperes (A), not watt-hours.
- Option B: Electric energy - Correct, as watt-hour meter directly measures electric energy.
- Option C: Power - Measured in watts (W), which is not the same as watt-hours since power is energy per unit time.
- Option D: Voltage - Measured in volts (V), not related to watt-hours directly.
