Resistance Coils 20 Ohm with Terminals

Description

Construction: These coils consist of a wire (often made of a material such as constantan or nichrome) accurately wound onto an insulating base or housed within a transparent plastic or bakelite casing. The coil is connected to two terminals for easy integration into circuits.

Resistance Value: Specifically designed to provide 20 Ohms resistance, they regulate current flow, dissipating electrical energy as heat safely.

Voltage & Power Rating: Typically rated for a maximum voltage around 4.4V with continuous power dissipation about 4 watts, and short bursts up to 10 watts. Care must be taken to avoid overheating.

Applications: Widely used in educational experiments, calibration, resistance measurement bridges, and circuits in physics labs for studying electric current behavior and Ohm's law.

Features: The presence of terminals simplifies connection and disconnection in lab setups. The coil's construction ensures minimal inductive effects, making it suitable for direct current (DC) and low-frequency AC experiments.
