Power dissipated by each resistor is described as considerably higher in parallel than in series when connected to:
AA current source only
BThe same voltage source
CTwo different sources
DNo source at all
Answer & Solution
Correct answer: B. The same voltage source
1. The comparison holds the source fixed.
2. Parallel connection lowers the total resistance.
3. More current therefore flows from the source.
4. The power dissipated by each resistor is considerably higher in parallel than in series.
5. The comparison is made when connected to the same voltage source.
