Question

(11%) Problem 7: Consider four identical bulbs connected in series to a battery. DAA fifth bulb is then connected in parallel with the first four. What will this additional connection do? Grade Summary Deductions 100% Potential 100% Leave the illumination produced by bulbs in series unchanged It will change illumination somehow, but we need to know the voltage on battery and resistances of bulbs to answer. Increase the illumination produced by bulbs connected in series. Decrease the illumination produced by bulbs in series Submissions Attempts remaining:3 33 per attempt) detailed view Submit Hiut edba I give up! Hints: 10% deduction per hint. Hints remaining: 1 Feedback: 0% deduction per feedback.

Explanation / Answer

Since 5th bulb is connected in parallel to the series combination of 4 Resistors, It will not affect the voltage and current of the series combination, and therefore

Answer: Leave the Illumination produced by bulbs in series unchanged
