AI Generated Solution

To find the number of electrons passing through the filament of an incandescent lamp that draws a current of 0.5 A over the course of one hour, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the given values:** - Current (I) = 0.5 A - Time (t) = 1 hour = 3600 seconds (since 1 hour = 60 minutes and 1 minute = 60 seconds, thus 60 * 60 = 3600 seconds) ...
