I know that P = VI where P is power in watts (joule/second), V is voltage in volts (joule/coulomb), I is electric current in amps (coulomb/second). My idea of work is like this. I use force (in newton) to pick up a stone and take it from point A to point B with a distance d in meters. I think that's work in joule (Work = Force x distance). If I would apply this to electricity, the stone pertains to an electron. My idea about power is, say I did what I did above in 1 second. Thus Power is equal to joule/second. Now my question is this. Say that the pressure (Voltage) is 120 V and the flow 10 Amps is less (electric current). That means I have 1200 Watts of power. What if I switch values as in 10 V, 120 Amps. This clearly states that the pressure (Voltage) now is less while the flow (electric current) is much. Now my question is this. In the situation where the pressure is high and current is low, shouldn't the power be less? And in the situation where the pressure is low and the current is high, shouldn't the power be much? I appreciate your ideas.
