Amperes, often referred to as “amps,” measure the flow of electric charge. One ampere is equivalent to one coulomb of charge passing through a conductor in one second. Amps are crucial when it comes to understanding how much current an appliance draws from the electrical supply.
What are Volts?
Volts (V) measure the electrical potential difference between two points. This potential difference is what drives electric current through a circuit. Household appliances in North America typically operate on a standard voltage of 120 volts.
The Relationship Between Watts, Amps, and Volts
The relationship between these three units can be expressed with the formula:
Power (W) = Voltage (V) × Current (A)
This formula lets you calculate the current draw (in amps) of any appliance if you know its wattage and the voltage of your electrical system.
Calculating the Amps for a 700 Watt Microwave
Now that we have a basic understanding of watts, amps, and volts, let’s calculate how many amps a 700 watt microwave requires. Using the formula mentioned above, we can rearrange it to solve for the current:
Current (A) = Power (W) / Voltage (V)
Assuming your microwave operates on a standard household voltage of 120 volts, the calculation will look like this:
Current (A) = Power (W) / Voltage (V)
Current (A) = 700 W / 120 V
Current (A) ≈ 5.83 A
So, a 700 watt microwave draws approximately 5.83 amps from your household electrical supply. It’s essential to note that this is an estimate, and the actual amperage can vary slightly based on factors such as the efficiency of the microwave and whether it has features like inverter technology or a more powerful cooking function.
