WebMay 31, 2024 · The issue in power transmission is to do it efficiently (at low cost) and safely. The power requirement is fixed. It is basically the voltage times current (forgetting power factor for the moment). The higher the transmission voltage, the lower the current for the same power. The lower the current, the smaller the wire size. WebHigh voltage electricity refers to electrical potential large enough to cause injury or damage. In certain industries, high voltage refers to voltage above a certain threshold. Equipment and conductors that carry high voltage …

WebJun 29, 2012 · 438. The main reason for higher current is the need for lower voltage. For a vehicle even 100 volts would pose a significant safety hazard.

To deliver 100W you can either have 50V and 2I or 25V and 4I. ...but looking at Ohms law, V =IR, if we want to have a higher voltage and lower current the resistance has to go up, e.g 50v = 2I x 25R or 25V = 4I x 6.25R.

WebOnline, most household wiring guides suggest 14 gauge wire for 15 amp circuits, 12 for 20 amps, and 10 for 30 amps. Do these assume the voltage is 120, or does voltage not come into play when choosing wire gauge? For example, I have an appliance that requires a 240 volt 15 amp power source. (Its plug is NEMA 6-15.) WebSo you can’t say “high voltage equals high current”. For a given resistive load, higher voltage will cause higher current. For a step-up or step-down transformer, the higher …
