That depends on what you mean. If you mean why does a circuit which has a high voltage side and a low voltage side have a greater average current on the low voltage side, it is probably because of power conservation: P = IV.
If this is not what you mean, you will have to be more specific!
If the resistance of the circuit remains the same, yes. E = I x R Formulas for you to use are E/I = R, E being voltage and I being current or amps.AnswerNot necessarily. For example, electricity transmission is only possible because, for a given load, the higher the voltage, the lower the resulting load current. So the answer is that it depends on the load'!
High resistance on the feeder to the load will cause voltage drop at the load end of the circuit. If this is happening, do the calculations for voltage drop, using the amperage of the load, voltage of the load, the size of the wire feeding the load and the distance from the distribution panel to the load.
A step up transformer converts low voltage,high amperage current to a high voltage,low amperage current. It requires large diameter wire to carry the high amperage in the primary coil.

Through a relay or some other kind of high voltage switching device.
High voltage the switch blade must be long enough to break the arc low voltage means a smaller switch low amperage means smaller wire and contacts 120V 1/2" switch 13,200V 18" switch vacuum switches can be made smaller since there is no air to ionize
In this case current flows from a high voltage to a lower voltage in a circuit.

The function of a choke in a lamp circuit is to produce high voltage. In tubelights, the high voltage is essential for ionisation of the gas which is present in tubelights.
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.
Air circuit brakers is not used in high voltages because, when comparing the high voltage the dielectric strength of air is low. By nandhagopal theni.ph 7200801043.
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.
