As you build circuits, you will alter voltage, which is the variable. You will measure how changing the voltage affects the current, which is the variable. A "constant" is a parameter that stays the same regardless of the other variables, and in this case, is held constant.

Loki · Answer 1

Independent, dependent, resistance

Alexandria Ferguson · Answer 2

Independent, dependent, resistance

Explanation:

An independent variable is the one which is varied to test changes in the dependent variable. In the given experiment, voltage is an independent variable is which is being varied and it's effect on current (dependent variable) is being tested. Resistance being held constant.

According to Ohm's Law, current is proportional to voltage.

V = I R

R is resistance
