Question

Как включается вольтметрв цепь?

Answer 1

Зажимы вольтметра присоединют к тем точкам цепи, между которыми наддо измерить напряжение. Такое включение называют параллельным. Положительный зажим нужно обязательно соединять с проводом , идущим от положитеельного полюса источника тепла.

How to Connect a Voltmeter in a Circuit

To connect a voltmeter in a circuit, follow these steps:

1. Turn Off the Power: Before connecting the voltmeter, ensure that the power to the circuit is turned off to prevent any electrical hazards.

2. Identify the Voltage Points: Identify the points in the circuit where you want to measure the voltage. These are typically the points where you want to measure the potential difference.

3. Connect the Voltmeter: Once the power is off and the voltage points are identified, connect the voltmeter in parallel to the component or points where you want to measure the voltage. The positive terminal of the voltmeter should be connected to the point with higher potential, and the negative terminal to the point with lower potential.

4. Turn On the Power: After the voltmeter is securely connected, you can turn the power back on and take the voltage reading.
