Work and Power

Work and Power. Work. Work happens when a force moves an object over a distance If the object does not move, no work is done For work to be done, the direction of the applied force must be the same as the direction of the motion. Work. You lift a bag of groceries

CIRCUITS, NODES, AND BRANCHES

CIRCUITS, NODES, AND BRANCHES. Last time: Looked at circuit elements, used to model the insides of logic gates Saw how the resistor and capacitor in the gate circuit model make the change in output voltage gradual Looked at the mathematical equations that describe the output voltage. Today:

Power

Power. Remember Work?. Work is a force times a distance I do the same work if it takes me 1 minute to walk up a flight of stairs or 1 day to walk up a flight of stairs Because work has nothing to do with time!. Power. Power is the rate at which work is done
