Question 269Electricity & Electronics - QMED

The correct answer is A) the power being consumed by electrical equipment. A wattmeter is a device used to measure and indicate the power being consumed by electrical equipment. It directly measures the product of voltage and current, which gives the power consumption in watts. This is the primary function of a wattmeter and is why option A is the correct answer. The other options are incorrect because a wattmeter does not measure partial circuit resistance (option B), voltage between two points (option C), or current flow (option D). Those are different electrical measurements that require other types of instruments, such as an ohmmeter, voltmeter, or ammeter, respectively.
