How would you describe the relationship between current and voltage in a series circuit?

In a series circuit, the relationship between current and voltage can be described as directly proportional due to Ohm's Law, which states that voltage (V) is equal to current (I) multiplied by resistance (R). This can be represented mathematically as V = I × R.

In a series circuit, the total resistance is the sum of the individual resistances, and the same current flows through all components. If you increase the resistance, the voltage across it will increase proportionally, given that the current remains constant. Conversely, if you increase the applied voltage while keeping the resistance constant, the current will also increase proportionally. This direct relationship means if one quantity increases, the other will also increase proportionally, showcasing that the current and voltage in a series circuit are indeed directly proportional.

Understanding this relationship is crucial for linemen as it aids in troubleshooting and designing circuits, ensuring that they function safely and effectively.
