#### 900 watt berapa ampere

To calculate the current in amperes for a 900 watt device, you need to understand the relationship between power, voltage, and current. The formula to find the current is: current (I) = power (P) / voltage (V). For a 900 watt device, if you are using a standard voltage supply of 230 volts, the current would be I = 900 / 230, which equals approximately 3.91 amperes.

### Understanding Power and Current

Power, measured in watts, represents the rate at which energy is used. Current, measured in amperes, is the flow of electric charge. By dividing power by voltage, you determine the amount of current needed.

### Voltage Considerations

Different regions use different voltage standards. Ensure you use the correct voltage value for accurate calculations. In some countries, the standard voltage is 120 volts, which would change the current calculation for a 900 watt device.

### Practical Application

Knowing the current required helps in selecting appropriate wiring and safety devices. Overloading circuits can lead to safety hazards, so it’s crucial to match the current with the circuit’s capacity.

In summary, calculating the current for a 900 watt device involves dividing the power by the voltage. Always consider the voltage standards and ensure that the circuit can handle the current to maintain safety and efficiency.
