The device used to detect the electrical current to the electric heater coil is called?

The device used to detect the electrical current flowing to an electric heater coil is known as an ammeter. This instrument is specifically designed to measure the flow of electric current in amperes, which is particularly relevant for understanding how much current is being drawn by the heater coil during operation.

By monitoring the current, an ammeter helps assess whether the heater is functioning properly and can provide critical insights into performance and efficiency. If the current is too high or too low, it could indicate potential issues such as a faulty heater or problems with the electrical supply.

In contrast, an anemometer measures wind speed, and an ohm meter is used to measure resistance in electrical circuits, which are not applicable to measuring current directly. A voltmeter measures voltage, which is important for understanding the electrical potential in a circuit, but it does not provide information about the amount of current flowing to the heater coil. Thus, an ammeter is the correctTool for this particular application.
