Higher Voltage Means Lower Current

Equipment and conductors that carry high voltage warrant special safety requirements and procedures.

Higher voltage means lower current. 1 kv kilo volt is equal to 1000 volts. The voltage is like the length of the lever arm while each electron in the current is like a piece of the force a finger to stretch the analogy. In certain industries high voltage refers to voltage above a certain threshold. Assume the power to be transmitted is p and.

High voltage low current and vice versa is a transformation of what is already there you are not swapping a battery or any voltage source with another. Another example can be found in high amperage dc power supplies for internet nodes and telecommunications points of presence typically 48 volts at 120 amps or more. An example of low voltage and high current can be found in welding equipment. Electricity transmitted at high voltage and low current.

High voltage electricity refers to electric potential large enough to cause injury or damage. E ir your understanding that an increase in voltage should result in an increase in current is correct swap out a 3v battery in a simple circuit for a 9v and you ve jumped 3x current as well. For getting power from the power station it required various types of power transformers and it operates on high voltage like 11 kv 33 kv 66 kv 110 kv 132 kv etc. Your short wrench low voltage might take both hands 8 fingers high current to loosen some bolt but twice as long a wrench high voltage might require half as much fingers current.

Which means you will get 132 000 volts stands on 132 kv transmission line. For example a car battery. Higher voltage is often used to send large amounts of power over long distances specifically because the current is lower and there is lower loss through the transmission system for example in the public power utility grid. The voltage current relation is focused on two things 1 the power which generated the electricity in the first place 2 the resistance r of the medium through which the current is supposed to flow.

But sometimes it is more efficient to use lower voltage and higher current.
