Frequently Asked Questions

An informative section offering quick responses to the most frequently posed questions by users or clients.

What is the formula to calculate electrical power from voltage?

The formula to calculate electrical power from voltage is P = V x I, where P is the power in watts, V is the voltage in volts, and I is the current in amperes

Can I calculate electrical power if I only have the voltage?

Yes, you can calculate electrical power if you only have the voltage by using the formula P = V^2 / R, where P is the power in watts, V is the voltage in volts, and R is the resistance in ohms

How can I use the power equation to find the current?

You can use the power equation to find the current by rearranging it to I = P / V, where I is the current in amperes, P is the power in watts, and V is the voltage in volts.
