(Voltage is effectively pressure,
Since you mentioned nerds, Voltage is potential. (probably most similar to Potenial energy in newtonian physics, i.e. you have more potential standing on top of a ladder than on just the first rung)
So an outlet is 110V but its only potential if nothing is actually plugged in. (it can do something but won't unless you make it, just like jumping off the ladder)
If anyone wants a simple analogy to visualize Ohm's laws:
picture a highway as a conductor (i.e. wire)
The cars are electrons.
Voltages is the number of cars between 2 points. (Volts)
Current is how fast the cars are moving. (Amps)
Resistance would be things causing them to slow down/congest (ohms) (lights, construction, accidents)
Power is a function of how many and how fast. (watts) (so many cars moving slower or fewer cars moving faster would generate a similar amount of power)
Of course the analogy breaks down in some ways and can't explain things like capacitance or inductance or transistor behavior etc...but hopefully gives someone a very loose idea how to visualize it and get through an intro to electronics class.
