Does voltage or current cause heat?

Does voltage or current cause heat?

Answer: Current causes heat. When current flows through a resistive material, it encounters resistance, leading to the generation of heat according to Joule’s Law (P = I²R). Reasoning: Voltage represents the force that drives current, and resistance impedes the flow of current. When current encounters resistance (R), it experiences a …
