Which electrical parameter remains identical through every component in a series circuit?
Which electrical parameter remains identical through every component in a series circuit?
Multiple Choice Options
- A
Voltage
- B✓ Correct Option
Current
- C
Power
- D
Resistance
Detailed Technical Solution & Explanation
According to Kirchhoff's Current Law (KCL) and the conservation of electric charge, there is only a single conductive pathway in a series circuit; therefore, the exact same electric current flows through every component connected in series.
Option Analysis:
•
Option A (Voltage): Incorrect. Voltage divides across components proportional to their impedances ().
•
Option B (Current): Correct. Current has only one loop path and remains identical throughout all series elements.
•
Option C (Power): Incorrect. Power dissipated differs based on individual component values ().
•
Option D (Resistance): Incorrect. Individual resistor values in series can be completely different.
