The four bulbs of 40 W each are connected in series swift a battery across them, which of the following statement is true_______________?
Correct answer: A. The current through each bulb in same
- A. The current through each bulb in same
- B. The voltage across each bulb is not same
- C. The power dissipation in each bulb is not same
- D. None of the above
Explanation
A series circuit has only one path, so the current through every bulb is the same. The voltage and power may differ if the bulbs have unequal resistances, but statement a is always true.
