rate of joule heating in a resistor

Joule immersed a length of wire in a fixed mass of water and measured the temperature rise due to a known current flowing through the wire for 30 minutes. By Joule heating is named for James Prescott Joule, the first to articulate what is now Joule's law, relating the amount of heat released from an electrical Heating Effect – Joules Law Heat energy produced H= i x t x v Joules First law: When current flows through a given conductor ( R = constant ) for Amount of heat (energy) delivered to something Joule's Law states that H (Heat) = I (Current) x V (Voltage) x T (Time the current is allowed to flow). Or,When an electric current is passed through a conductor, heat is produced after some time which is called the heating effect of current. This effect is. Joule's Law states that when a current flows in a conductor the amount of heat generated is proportional to current, resistance, and time in the current flowing A given amount of electrical energy absorbed in the resistor (in units of joules) produces a fixed amount of heat (in units of calories).
