Question

In Ohm's Law, it states that the current in the circuit is directionally proportional to the voltage in that circuit. Explain what you understand stand by this.​

Answer 1

Answer:

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.
