what is short to voltage in a car electrical circuit & how to check it ?
A: As soon as a DC voltage is applied the capacitor is a short or no voltage
to the floor
A short to voltage is when a wire that should not have battery voltage has battery voltage. This would happen if a wire had rubbed through another wire. The other cause would be an electrical component failing and sending voltage down a wire that it shouldn't. NOTE: Shorts to voltage are very uncommon. I specialize in electrical automotive repair, and I can not even recall one time I have seen a short to voltage.
In Short circuit test High Voltage side is feeded with 2-5% of the High Voltage rating to circulate approximately full load current in low voltage winding by short circuiting it. Low voltage is generally short circuited to facilitate measurements because it is more difficult to measure the quantities at high voltages.
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.
zero? the supply voltage? the supply voltage minus the individual coltage drops? the sum of the individual voltage drops? which one?
A short circuit is an abnormal connection between two nodes intended to be at different voltages. A voltage circuit is caused intentionally for the purpose of voltage sensing. A ground circuit occurs between a phase and the ground.
If a short occurs in a resistor in series with other resistors, the voltage drops across the other resistors will increase. If a short occurs in a resistor in parallel with other resistors, the voltage drops across the other resistors will decrease, to zero.
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
Short circuit voltage is the voltage that has to be applied to the primaries of a transformer, so that the nominal current flows through the secondaries, when they are shorted. This value is important, if transformer secondaries shall be used in parallel. Ideally all transformers with parallel secondaries should have the same short circuit voltage. When their short circuit voltages are different, the transformer with the lower short circuit voltage will be loaded more than their relationship of power ratings would predict. The short circuit voltage is also important in the design of a transformer, because it predicts, how much the secondary voltage will drop at nominal output current. This knowledge helps the designer to find out, how many further windings the secondary needs for a certain voltage in relation to an ideal transformer. Short circuit voltage is also known as impedance voltage.
The output short circuit current is the solar cell's current when the voltage is zero, or when it, is short circuited.
