Text Solution

AI Generated Solution

To find the largest voltage that can be safely applied across a resistor marked `196 Ω` and `1 W`, we can use the relationship between power, voltage, and resistance. ### Step-by-Step Solution: 1. **Understand the Power Formula**: The power (P) dissipated by a resistor can be expressed in terms of voltage (V) and resistance (R) using the formula: \[ P = \frac{V^2}{R} \] ...
