Final answer:
The query involves finding the instantaneous current in a wire for a given charge function over time, a concept in high school level physics.
Step-by-step explanation:
The question is about calculating the instantaneous current in a wire given the charge as a function of time. In physics, current is defined as the rate at which charge flows through a point in a circuit. The SI unit for current is the ampere, which is equal to one coulomb per second. Instantaneous current can be found by taking the derivative of the charge function with respect to time.
For the given function q (t) = qoe-t/T, the initial current at time t = 0 can be found by substituting t = 0 into the derivative of the charge function. In part (b), to find the current at time t = T, we substitute T for t in the derivative.
