Assume that an automobile has a 15 gallon fuel tank, and it is possible to refill the tank in 5 minutes. The fuel tank contains 33 kWh per gallon. If the vehicle were to be replaced by an electric vehicle that charges from the power grid, how much power would it draw (in W, kW, or MW) to recharge at the same rate as the gasoline powered automobile?
A Tesla Model S contains an 85 kWh battery and can be charged at a rate of 22 kW. Assuming no losses (100% efficency), how long (in hours) will the car take to charge?
The gasoline powered car has a range of 375 mi, and the Tesla Model S has a range of 300 mi. How much more efficient in terms of miles per kWh is the Tesla than the gasoline powered car?
An ideal voltage source produces a dirac delta function, an impulse spike to a series resistor, capacitor combination. R = 10.000 ohms, C = 0.039 uF. Calculate the initial voltage that the capacitor charges to at t = 0+.

The following measurement were made on a two-port resistive circuit. With port 1 open, V2 =15V, V1 = 10 V, and I2 = 30 A. With port 1 short-circuited, V2 = 10 V, I2 =4 A, and I1 = -5 A. Find the parameters of the z-parameter two-port.
a) Design the doubler circuit shown in Figure 2, for which:D = d8 d4 d2 d1 and B = b8 b4 b2 b1 are each an 8421 BCD code digit. The circuit must implement the equation: 10C* + B = 2D + C
What kind of wireless networking alternative makes the most sense when considering network links that span an appreciable portion of the globe?
The feedback system for the Buck circuit can be analyzed by separating DC component from small signal perturbation. The performance of the feedback can be assessed by examining the Bode plot of the loop transfer function GL(s).
