State three rules concerning parallel circuits.

Question

StudyXY · Accepted Answer

**Equal voltage distribution:** In a parallel circuit, the voltage across each component is equal to the source voltage. **Total resistance calculation:** In a parallel circuit, the total resistance can be calculated using the formula $$\frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + ... + \frac{1}{R_n}$$, where $$R_1, R_2, ..., R_n$$ are the individual resistances of each branch in the circuit. **Current division:** In a parallel circuit, the total current supplied by the source is divided among the branches, and the current flowing through each branch is inversely proportional to its resistance. The three rules concerning parallel circuits are: 1. Equal voltage distribution: $$V_{component} = V_{source}$$ 2. Total resistance calculation: $$\frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + ... + \frac{1}{R_n}$$ 3. Current division: $$I_{branch} = \frac{\frac{V_{source}}{R_{branch}}}{\frac{V_{source}}{R_{1}} + \frac{V_{source}}{R_{2}} + ... + \frac{V_{source}}{R_{n}}}
