1K resistance connected to the two ends of 220V, equivalent to how many watts How to use in other voltage calculation, it is best to give a formula
First calculate the current, according to the formula I = u / R, I = 1000 / 220, I = 0.22a
Then calculate the power according to the formula P = u * I, P = 220 * 0.22, P = 48.4w
