Question

Как узнать проходит ли в проводнике ток?

Answer 1

Ответ:

Поднеси компас, если течёт стрелка отклонится.

Объяснение:

О наличии тока в проводнике можно судить по действиям которые ток оказывает. При прохождении тока всегда наблюдается тепловое действие и магнитное. Проще всего заметить проявления магнитного действия. Если вблизи проводника происходит отклонение магнитной стрелки. то в проводнике идет ток. Естественно, речь идет о постоянном токе.

Checking the Flow of Current in a Conductor

To determine if current is flowing in a conductor, you can use a multimeter to measure the current. Here's how you can do it:

1. Set the Multimeter to Measure Current: - Set the multimeter to measure current in the appropriate range. Make sure to select the correct range to avoid damaging the multimeter.

2. Connect the Multimeter in Series: - Connect the multimeter in series with the conductor through which you want to check the current flow. This means the current will flow through the multimeter.

3. Read the Measurement: - Once the multimeter is connected, it will display the amount of current flowing through the conductor.

It's important to note that when measuring current, the multimeter must be connected in series with the circuit to accurately measure the current flowing through the conductor.

This method allows you to directly measure the current flowing through the conductor and determine if there is a current present.
