WebAug 10, 2024 · For example, an AC current with an RMS value of 1 A causes the same heating effect as 1 A of DC. When AC flows through a resistance, the power dissipated is constantly changing with the AC sine wave. The power dissipated at any instant can be calculated by applying the following formula: P D = I 2 × R. Where. P D = power … WebAC voltages can vary widely (between -10% and +5% of the power source rating) and cause no problems in a circuit. Yet with dc voltages, even small variations may indicate trouble. The exact amount of acceptable dc voltage variation depends on the application. See chart below for an example. hand peace sign on keyboard
