About: Weston Ammeter and Resistor

The Weston ammeter and Weston resistor are both precision instruments made by Edward Weston, an American electrical engineer. The ammeter is used to measure thethe electric current flowing through a circuit (in amperes). 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 ammeter, ensuring precise measurements. Both instruments contributed significantly to advancements in electrical measurement technology.
