About electric current

Electric current is the flow of electric charge. One ampere is one coulomb of charge passing a point each second. Since 2019 the ampere has been defined by fixing the value of the elementary charge.

Small electronics work in milliamperes and microamperes: an LED draws around 20 mA, and a microcontroller in sleep mode may draw only a few microamperes. Household circuits are rated in amperes, typically 10 to 32 A.

To find current from power, divide watts by volts: a 1,200 W kettle on a 240 V supply draws 5 A.

Frequently asked questions

How do I convert watts to amps?

Divide the power in watts by the voltage. For example, 600 W at 120 V is 5 A.

How many microamps are in a milliamp?

There are 1,000 microamperes in one milliampere.
