How do you find minimum power?
Use the formula for power: Power = Voltage x Current, or P = VI.
If you are trying to calculate the minimum load and you happen to only know the power and voltage ratings of your power supply, you can use the formula P = V2/R, which can become R = V2/P..
Can power be negative?
The sign of power is just a matter of definition. Energy can increase or decrease, but the energy itself cannot be negative. … As you said, power is just the time rate of change of energy, so it can be negative. But energy is only positive.
How do you calculate total power?
Power can also be calculated using either P = IV or P=V2R P = V 2 R , where V is the voltage drop across the resistor (not the full voltage of the source). The same values will be obtained.
What is the power in science?
Power, in science and engineering, time rate of doing work or delivering energy, expressible as the amount of work done W, or energy transferred, divided by the time interval t—or W/t.

How do you find power?
Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.
What is the work of power?
Also, when work is done, an equal amount of energy is consumed. Thus, power is also defined as the rate at which energy is consumed or utilised. The S.I unit of power is watt (W). One watt is the power of an appliance which does work at the rate of 1 joule per second.
