Nettet7. sep. 2024 · Joule’s Law states that H (Heat) = I (Current) x V (Voltage) x T (Time the current is allowed to flow). Or, written differently, H (Heat) = I2 (Current squared) x R … NettetThe heat a resistor produces is the energy loss given by I2 R. If you assume a fixed voltage and resistance, then. I= V/R so the heat produced is given by. (V/R)2(R) = V2 / R. Look at the math. Lower resistance will produce more heat because more current flows.

"Nettet24. jul. 2024 · From Joule's laws, we get this: H ∝ I 2 R t H = K I 2 R t... ( i) Now, we have to find/define the value of K. According to my book, when 1 A of current passes through a conductor of 1 Ω for 1 s, 1 J heat is produced. If that's the case, then from ( i) we get this: 1 = K × 1 × 1 × 1 K = 1 Therefore, we get our nice little formula: H = K I 2 R t " - Joule's law of heating formula
