WebAccording to Joule 's law of heating, heat produced H = I2Rt, where I is current, R is resistance and t is time. If the errors in the measurement of I, R and t are 3%, 4% and 6% respectively then error in the measurement of H is (1) ± 17% (2) ± 16% (3) ± 19% (4) ± 25% Q 226: 89 % From NCERT (1) (2) (3) (4) Subtopic: Errors Show Me in NCERT WebThe metal element inside a fuse is designed to melt through Joule heat produced by overcurrent, thus interrupting the current flow in the circuit. Because the Joule heat (I2Rt) required to melt the metal element differs based on the ambient temperature, the time at which the metal element in the fuse will reach its melting point will also vary.
