Question
In a series circuit, the current is __________ at every point around the circuit.
Which of the following completes the sentence?
different
equal
Solution
In a series circuit, the current is equal at every point around the circuit.
Explanation:
In a series circuit, all components are connected end-to-end, forming a single path for the current to flow. Since electric current (measured in Amperes) is the flow of electric charge, it remains constant throughout the circuit. This means that the same amount of current that exits one component must enter the next, ensuring that the current remains equal at all points.
This principle can be understood through Ohm's Law, which states:
Where:
- = Voltage,
- = Current, and
- = Resistance.
In a series circuit, while the voltage may vary across different components (depending on their resistance), the current flowing through each component remains the same. This characteristic distinguishes series circuits from parallel circuits, where the current can vary across different paths.
