Current and power relationship
WebPower is defined as the rate energy ( \text U U) is transformed or transferred over time. We measure power in units of joules/second, also known as watts. An electric circuit is capable of transferring power. … WebNote that since power loss is proportional to the square of the current being transmitted, that is: I 2 R, increasing the voltage, let’s say doubling ( ×2 ) the voltage would decrease the current by the same amount, ( ÷2 ) while delivering the same amount of power to the load and therefore reducing losses by factor of 4. If the voltage was ...
