1.The realistic power output of a crystalline solar module operating at 65 degree C as a percentage of its rated nameplate power output is approximately what % of STC?

2. If a STC value for Voc is 20V and Isc is 4A and irradiance is at a half sun, what would be the approximate Voc and Isc?

When a shorting type rotary switch is turned each contact is shorted to a common bar simultaneously.

what is the theory (general principles) of KVL and KCL? please explain, when its applicable, consist of etc please write neatly preferably typed and go into detail please.

also what is a voltage divider?

An Induction machine rotates faster than synchronous speed and puts real power to the grid. Does it send reactive power to the grid as well?

Use SVD method to compress and decompress images in the MATLAB.

Compression function. The input is an image file and k. The output is a text file containing the reduced U, V , and the reduced diagonals of ?.

Decompression function. The input is the output of the compression code. The output is an image (you can use imshow for this purpose).

A 1000MVA, 20kV, 60 Hz three phase generator is connected to an infinite bus through a 1000MVA, 20kV? / 345kVY transformer to a 345kV circuit breaker and a 345kV transmission line. The generator reactances are X``d=0.17, X`d=0.30, and Xd=1.5 per unit on a 1000MVA, 20kV base. Generator time constants are T``d=0.05 seconds, T`d=1.0 seconds, and TA=0.10 seconds. The transformer series reactance is 0.10 per unit on the transformer ratings as a base. Neglect transformer losses, excitation current, and transformer time constants. The far end of the line is considered to be an infinite bus operating at 1.0 per unit voltage on the transformer ratings as a base. The line reactance is +j0.20 per unit on the same base as everything else. A three phase short circuit occurs on the line side of the transformer when the generator operates at no load. Breakers interrupt the fault three cycles after it begins. Determine the subtransient current through the transformer in per unit and the rms asymmetrical fault current that the breakers interrupt assuming maximum dc offset.
