Question

The potential in a circuit, V, is a function of time, t, with

V(0) = 12 volts, and dV/dt = −18e^−1.5t volts/sec. Find V(0.5). Be accurate to ±0.1 volts.

V(0.5) = _____________

Answer 1

This is a simple differential equation with general solution

V=-12e^-1.5t + C and the constant determined from the initial condition is 24.

You can calculate the answer from this equation.
