If you were going to describe the relationship between current, voltage, and power, you could say:

"If there is a decrease in power, there must have been an increase in either current or voltage."
"If you decrease your voltage, and all other factors remain the same, you will have an increase in power."
"In order to gain more power you would need to increase either current or voltage."
"The only way to increase your power is to change your voltage and keep your current the same."
