When attempting to lower power loss by reducing current, what must be raised by the same proportion?

When seeking to lower power loss in an electrical system by reducing current, it is essential to increase voltage by the same proportion to maintain the same level of power delivery. This relationship is grounded in the principles of electrical power formulas, specifically ( P = IV ), where power (P) is the product of current (I) and voltage (V).

When current decreases, if voltage does not increase, the overall power delivered to a load will also decrease, potentially leading to insufficient power supply for operations. By increasing voltage proportionately to the reduction in current, the power can remain consistent even when current is lowered. This balance ensures that the power loss, which is typically calculated using the formula ( P_{\text{loss}} = I^2R ) (where ( R ) is resistance), can be minimized. In essence, maintaining power levels while effectively lowering current involves a proportionate adjustment in voltage.
