Heating power resistor
WebSolution - Derivation of Relation between Effective and Peak Value of Alternating Current. We describe the power delivered by a resistor in the DC circuit with the formula: P = V I. We rewrite this relation using Ohm’s law: V = I R. into the form that features the resistance of the resistor and current: P = R I 2. Web4 de feb. de 2024 · I would work this out by splitting the problem into two parts: work out the power when at + 4 V and when at − 2 V. Lets start with 4 V. Over a second you can work out that the resistor is at 4 V for half the time. The energy dissipated in a second when at 4 V is therefore: 4 2 20 × 0.5 s e c o n d s = 0.4 J.
