Volts and Current are:

Explanation:
Directly proportional. Ohm’s law tells us I = V / R. When the resistance is fixed, the current changes in step with the voltage: double the voltage and the current doubles as well. On a graph of current versus voltage, you’d see a straight line through the origin with slope 1/R, demonstrating a linear, direct proportionality. The other relationships would require nonlinear behavior (quadratic or exponential) or inverse behavior, which isn’t what happens with a simple resistor. In practical alarm circuits, treating loads as resistive helps you understand this linear relationship: increasing voltage, with the load staying the same, increases current proportionally.
