A ‘c-core' inductor has a total air-gap length of 3 mm and a cross-sectional area of 100 cm2. Two coils are wound on the core - one of 500-turns and another of 250-turns. Assuming the iron reluctance, fringing flux and leakage flux to be negligibl..
A parallel-plate capacitor has capacitance 9.00 µF. (a) How much energy is stored in the capacitor if it is connected to a 9.00 V battery (b) If the battery is disconnected and the distance between the charged plates doubled
aluminum has the FCC crystal structure. Its atomic weight is 26.98g/mole, and its density is 2.70g/cm3. Determine the atomic radius of a single aluminum atom.
A zener regulator circuit has a load resistance that varies between 470 ohms and 2700 ohms. The circuit uses a 10V zener diode, Rs = 330 ohms, and the source voltage is 24V. The zener resistance is 10 ohms and the zener test current (Izm) is 28mA.
Calculate the inductive reactance per meter of a single-phase, 50-Hz, two-wire transmission line. Assume each conductor's radius is 9cm and the distance between the two conductors is 5m.

Perform a link budget for a 25-kilometer point-to-point microwave link in the 30 GHz band. Calculate the free space loss (dB), received power dBm), fade margin (dB), and Fresnel zone radius(m) given the following: Tx Power = 70 dBm
A transformer is used to match an 8 ohm speaker to a 500ohm audio line. What is the turns ratio of the transformer what is the input voltage and output voltage when 15W is being delivered to the speaker
Consider a portable 20cm2 fuel cell operating at 0.75V, 0.6 A/cm2. Suppose the stoichiometry of the anode is 2.0 and that of the cathode is 2.3. The fuel cell is expected to run for 3 days before being recharged.
Describe the difference between a N-Channel and a P-Channel CMOS transistor when a signal is applied to the gate
Using MatLab, create and graph the pairwise convolution of the following functions (i.e., A must be convolved with B, C, D, and E, individually. B must be convolved with C, D, and E, individually, Etc.). All time scales are -4 to +4.
