About: Weston Wattmeter and Resistor
The Weston wattmeter and Weston resistor are both precision instruments made by Edward Weston, an American electrical engineer. The wattmeter is used to measure the power consumed by an electrical circuit in watts, calculating power by measuring voltage and current. Known for its accuracy, it was widely used in laboratories and industries. The Weston resistor, on the other hand, is a stable and reliable standard resistor used for calibrating electrical instruments like the wattmeter, ensuring precise measurements. Both instruments contributed significantly to advancements in electrical measurement technology.
