NettetAccording to Joule's law of heating, if heat H is being produced in a wire then H∝I 2 H∝R H∝t where I is current in wire R is resistance of wire and t is the for which current flows. Combining all factors Heat produced in a wire is given by H=I 2Rt in Joule Applications of Joule's heating effect in daily life : NettetJoules law can be stated as the quantity of heat generated (H) in a conductor of Resistance (R), when a current (I) flows through it for a time (t) is directly proportional to the square of the current, the resistance of the conductor, and the time for which the current flows. So, H=I 2Rt. Now, for a conductor following Ohm's Law, V=IR, or, I ...

NettetJoule heating described quantitatively is that the heat evolved per second, or the electric power loss, P, equals the current I squared times the resistance R, or P = I2R. The … NettetJoule’s Law states that “If “I” amperes current flows through a resistor “R” for “t” seconds, then the amount of work done (conversion of electrical energy into heat energy) is … smt 4 differences anarchy

Heating Effect of Current Class 12 Physics Notes

NettetJoule equivalent of heat and given the symbol J. The Joule equivalent of heat is the amount of mechanical or electrical energy contained in a unit of heat energy. The factor is to be determined in this experiment. Power is defined as the rate of doing work, and electrical power is defined as the amount of electrical energy being expended per ... Nettet2 dager siden · In the electrically conducting flow regime, electric and magnetic fields are perpendicular to each other and Ohmic heating is appropriately handled in energy equation via Ohm’s law. NettetThe Joule heating effect (or resistive heating effect) denotes a phenomenon where electric energy is converted into thermal energy as an electric current flows through … smt 4 choices
