WebApr 7, 2024 · Ohm's Law tells us that V = IR. Substitute IR for V in the first formula: P = (IR)I = I 2 R. Rearrange to solve for resistance: R = P / I 2. In a series circuit, the current across one component is the same as the total current. This is not true for a parallel circuit. 3 Find resistance from power and voltage. WebOhm’s Law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions, such as temperature, remain constant. Part of... WebOhmic and Non-Ohmic Conductors Conductors which obey Ohm’s Law have a constant resistance when the voltage is varied across them or the current through them is increased. These conductors are called ohmic conductors. A graph of the current vs. the voltage across these conductors will be a straight-line. birth ideas
