Answer : 3. "Both A & B"
Explanation :
Answer: C) Both A & B Explanation: Brightness of bulb depends on both voltage and current. The brightness depends on power. Since we know that Power (P) = Voltage x Current = V I So whether you increase the current or the voltage the brightness will increase. Example Illustration: If you connect a long bulb and a round bulb in series, the long bulb glows but the round bulb does not. Both of them have the same current flowing through them (they are in series) but the long bulb has a greater voltage across it because it has more resistance (even though V= IR is not obeyed exactly, voltage drop does depend on the resistance). If you connect a round bulb and a long bulb in parallel, however, it is the round bulb that is brighter because now the voltage across both bulbs is the same but the current is larger through the round bulb (smaller resistance). Hence, the brightness of a bulb depends on power i.e, both voltage and current.
