          Problem 1.18
The voltage and current at the terminals of the circuit
element in the figure are zero for $t < 0$. For $t \ge 0$ they
are
v = 50$e^{-1600t} - 50e^{-400t}$ V,
i = 8.0$e^{-1600t} - 8.0e^{-400t}$ mA. (Figure 1)
Find the power at $t = 650 \mu s$.
Express your answer to two significant figures and include the appropriate units.
$p = 39.12 mW$

Problem 1.18
The voltage and current at the terminals of the circuit
element in the figure are zero for t < 0. For t ≥ 0 they
are
v = 50e^-1600t - 50e^-400t V,
i = 8.0e^-1600t - 8.0e^-400t mA. (Figure 1)
Find the power at t = 650 μ s.
Express your answer to two significant figures and include the appropriate units.
p = 39.12 mW
