A pn junction for which the breakdown voltage is 10 V has a maximum safe power dissipation of 0.5 W.
a) What continuous current in the breakdown region will raise the dissipation to half the rated value ?
b) If the breakdown occurs for only 1 ms in every 10 ms, what average breakdown current is allowed ?
The open circuit test on a single-phase 15kVA, 7500/480 V, 60 Hz distribution transformer yielded the following: V = 7500V; I = 0.2006A; P = 180W Calculate the core parameters RC and XM and the magnetizing current IM.

The electric field in a region of space is E= 4 ax V/m and the magnetic flux density is B= 5 az Wb/m2. At t= 0 a particle with mass 1 kg and charge 1 C is located at the origin traveling at a velocity of u0= 10 ay m/s.
A 50 ohms lossless transmission line is to be connected to a load of 25 ohm. Use a lamda/4(quarterLamda) length of line of unknown impedance between the load and the 50-ohm line to match it,
What are the transfer function and the impulse response of the system?
An unmanned X-43A scramjet test vehicle has achieved a maximum speed of Mach number 9.68 in a test flight over the Pacific Ocean. Mach number is defined as the speed of an object divided by the speed of sound.
