Answer:
A)
Explanation:
- In a series circuit, if we assume that each bulb has a resistance R, the equivalent resistance, is the sum of all the resistances, in this case, 3*R.
- The power dissipated in this resistance, can be expressed as follows:

- In the parallel circuit, the equivalent resistance, is equal to 1/3*R.
- The power dissipated in this resistance, can be expressed as follows:

- In order to take the ratio of both powers, we can divide both sides of (1) and (2) , as follows:

- The ratio of power dissipation in the parallel circuit to that in the series circuit is 9 times.
