To solve the problem, we need to find the current \( I \) at time \( t = 2 \) seconds, given the charge \( q(t) = 2t^2 + 3t + 1 \). ### Step-by-Step Solution: 1. **Understand the relationship between charge and current**: The current \( I \) is defined as the rate of change of charge with respect to time. Mathematically, this is expressed as: \[ I = \frac{dq}{dt} ...
