Question

For a constant resistance, how is the voltage related to the current?

Answer 1

The answer is:  Voltage is directly proportional to current, so when the voltage doubles, the current doubles (V=I*R).

The relationship between voltage, current, and resistance is presented by Ohm's law.

Answer 2

Answer:
Voltage is directly proportional to current, so when the voltage doubles, the current doubles.
Explanation:
voltage, current and resistance can be related to each other using Ohm's law which can be stated as follows:
V = IR where:
V is teh voltage
I is teh current
R is the resistance

Now, assuming that the value of R is constant, we can note that as the current increases, the voltage increases by the same value of increase and vice-versa

This means that, at constant resistance, the voltage and current are directly proportional to each other.

Hope this helps :)
