1. The problem asks to solve the first question from the provided document, which is about calculating the resistance in a circuit using Ohm's Law. 2. Ohm's Law formula is given by $$V = IR$$ where $V$ is voltage, $I$ is current, and $R$ is resistance. 3. To find resistance, rearrange the formula: $$R = \frac{V}{I}$$. 4. Substitute the given values for voltage and current into the formula. 5. Perform the division to find the resistance. 6. If the problem involves multiple resistors, use series and parallel resistance formulas: - Series: $$R_{total} = R_1 + R_2 + \cdots + R_n$$ - Parallel: $$\frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + \cdots + \frac{1}{R_n}$$ 7. Simplify the expressions step-by-step, showing all intermediate calculations. 8. Provide the final answer with units.
