15a 125v意思

"15a 125v" is a rating or specification typically found on electrical devices, components, or systems. Here's what each part means:

• 15a: This stands for 15 amperes, which is a measure of electrical current. It indicates that the device or circuit is designed to handle a maximum current of 15 amps. Amperage is the amount of electrical power that can flow through a circuit or device.

• 125v: This stands for 125 volts, which is a measure of electrical potential difference (voltage). It indicates that the device or circuit operates at a voltage of 125 volts. Voltage is the pressure that causes electricity to flow through a circuit.

When you see these two numbers together, they specify the electrical requirements or capabilities of the device or circuit. For example, a light fixture or an appliance might have a label indicating that it requires 15 amps and operates at 125 volts. This means that it should be connected to a circuit that can supply 15 amps of current at 125 volts.

It's important to note that the voltage rating (125v) is often associated with electrical systems in countries that use 120-volt AC power, such as the United States and Canada. In other parts of the world, different voltage standards may apply, such as 230 volts or 240 volts. Always ensure that electrical devices are used with the correct voltage to avoid damage or electrical hazards.
