Heat dissipated by resistor formula
Web12 de sept. de 2024 · Here, we note the equivalent resistance as Req. Figure 10.3.5: (a) The original circuit of four resistors. (b) Step 1: The resistors R3 and R4 are in series and the equivalent resistance is R34 = 10Ω (c) Step 2: The reduced circuit shows resistors R2 and R34 are in parallel, with an equivalent resistance of R234 = 5Ω. Web4 de oct. de 2013 · The value of the real power (P) consumed by the resistor is: Power = Voltage x Current (P = V x I) Since we already know that an applied Voltage (V) is required to force Current (I) through a resistor (R), another way of defining Power is: Power = (Current) 2 x Resistance (P = I 2 x R) Figure 1 – Heat vs. Current in a Resistor
