Open circuit test shows total voltage of a source such as a battery, transformer, energized circuit. Often, solar panels list open circuit values. The purpose is to prove that the design or nominal voltage is present. For solar panels open circuit voltage proves that the individual cells are connected and connected correctly. Open circuit values can be the standard to quality check two or more sources or circuits that have equal factory standards. Other uses: generators compare open circuit voltage exciter winding to actual useable output voltage winding for the purpose of correcting output with a signal to voltage regulator-Voc is an ideal reference; open ckt test can be used to test wire insulation for holes or damage because Voc can be made to go so high it will force an arc through damaged insulation; Voc tests are used to locate voltage or detect intact wiring or severed wires. Many more uses in electronic devices like high z input to digital tristate gates. High Z is open input, which is stable "on", applied voltage is timed pulse train, and ground is active "off"
The one thing to remember, open circuit tests always mean no current, no heat, no wear, no battery drain, but never believe no shock hazard. Voc will shock and can arc and start fires.
An open-circuit test is done on a transformer to isolate and measure those losses known as 'iron losses' that are due to eddy currents in the magnetic iron core of the transformer. Because the currents in the windings are very low the 'copper losses' are negligible. However the iron losses depend only on the applied voltage.
electrical and electronics engineering or electronics engineering as panels are electronic material ,or may be electrical engineering which deals with power generation
To improve the power factor
yes
mechanical,electrical engineering
electronic engg deals with the ic's ,active and passive elements and circuits and electrical power engg deals with the electric generation distibution and protection.
The load that is connected to the circuit is what draws the power of the electrical circuit.

Electrical engineering is low voltage, logic circuits, communications etc. Power engineering is electrical transmission and the like.You want EE.
To supply power to all electrical devices in a house, apartment, condominium, etc. A branch circuit is connected to the circuit breaker panel which is usually found in a closet or a cupboard
There has been some evidence that there is an increasing voltage relative to ground with increasing altitude. Creating any electrical power would be a matter of design engineering.
yes ,he can switch to electrical power or electronic engineering ,but has to learn a lot in these fields ,both in theory and practical
For calculation of I^2R losses nd it is also used for to evalute the damage in field

The syllabus for the electrical part of the ISRO exam covers things like basic technology related to electricity, circuit theory, electromagnetic fields, and the analysis of power systems.
The electrical engineering 3 phase is calculated by mathematics. The total active power is equivalent to three times the power of an individual phase.
