how to interpret FTIR data analysis? Explain it step by step.

Consider two electric bulbs. Bulb #1 has a resistance of twice as large as bulb #2.
Part (a) These two bulbs are included into a circuit in such a way that the voltage drops across them is equal. What bulb will produce the greater illumination?
The both will produce the same illumination.
It is impossible to answer without actual values of resistances.
Bulb #1
Bulb #2

Now these two bulbs are connected in a circuit so that current flowing through them are the same. Which bulb will produce the greater illumination now?
The both will produce the same illumination.
It is impossible to answer without actual values of resistances.
Bulb #2
Bulb #1
