Like I understand wattage and that a light bulb uses way less watts than say an electric dryer. But what causes less current to be supplied to the light bulb vs the dryer? I assume the power being supplied by the grid wants to force electricity out at a constant rate. So what is built into various circuits that causes the appliance to accept current at a higher or lower load? Is it simply just resistance? I can’t seem to wrap my head around this one.

edit: ignore me, I don’t know what I am talking about (well, I have some clue, but am not explaining it correctly)
~~There is a fixed relationship between voltage, current and load (resistence).~~
~~The voltage is essentially fixed, the load is set by the device concerned (which can vary depending on how much work is being done e.g. stage of washing cycle, more constant with a light bulb unless efficiently dimmable).~~
~~Thus, the current is different between devices (and between stages of their operation) to balance out the equation between voltage, resistence and current.~~
~~Voltage is equal to current times resistence.~~

~~The above is about direct current but this is also true in an AC circuit when the alternating current and voltage are in phase. That is, when the circuit is resistive.~~
