WebJul 10, 2024 · There are two possible formulas for power dissipation. The first one requires you to know resistance and current: P = R\cdot I^2 P = R ⋅ I 2. Alternatively, if you know the current and the voltage drop, you can use the other formula for power dissipation: P= V\cdot I P = V ⋅ I. The two equations are totally equivalent, and at a quick glance ... WebTake these two resistors in parallel, and think about what the equivalent resistance would be. And we have seen that before. One over the equivalent resistance is going to be equal to one over 6.0 ohms plus one over 12.0 ohms. 1/6 is the same thing as two over 12. So 2/12 plus 1/12 is 3/12. And 3/12, you could view that as the same thing as one ... WebSo, using the above circuit diagram as our reference, we can apply these formulas to determine the power dissipated by the resistor. Voltage = 9V Resistance = 100Ω I (current) = 9V / 100Ω or I (current) = 90 mA P (power) = 90 mA × 9V or P (power) = 0.81 W or 810 mW P (power dissipated) = V 2 (voltage) ÷ R (resistance) or that\u0027s phucked site
