Answer:
Step-by-step explanation:
Well mathematically it would look like this
E = k * I
k is the constant of proportionality.
As the voltage goes up, so does the current.
As the voltage goes down, so does the current.
In physics and engineering,, the formula is written somewhat differently.
E = I * R
The R is a device which limits the current. If R = 0 (like it is just a switch closing) then the first thing you will notice is that the lights go out and you better know where the circuit breakers are and have a flashlight to see which one you shorted out.
So R has a value > 0 in practice.
