Final answer:
Ohm's law relates the amplitude of voltage and resistance in electric circuits, defining how voltage drives current while resistance impedes it, thereby affecting the flow and steady state of current.
Step-by-step explanation:
The amplitude of voltage in an electrical circuit is related to the concept of resistance by Ohm's law. The voltage, or electrical potential energy difference, serves as the driving force that pushes current through a circuit. However, resistance is the property that impedes the flow of current, analogous to how friction impedes motion. The movement of charges through a material involves collisions with atoms and molecules, which limits how easily current can flow. Resistance is mathematically defined as inversely proportional to current, indicated by the relation V = IR, where V is voltage, I is current, and R is resistance. When resistance increases, less current flows for a given voltage, and this is called an IR drop across a resistor. Moreover, how the resistance affects the circuit depends on whether it's part of a parallel or series configuration. Through experimentation, it's observed that as resistance increases, the time to reach a steady state in a circuit either slows down or speeds up, depending on the configuration of the circuit elements.
