The figure below shows three lightbulbs connected to a 120-V AC (rms) household supply voltage. Bulbs 1 and 2 have a power rating of 75 W, and bulb 3 has a 40-W rating.

[Diagram Description: The diagram depicts three lightbulbs arranged in parallel, each connected to a 120-V AC power source.]

(a) Find the rms current in each bulb.
- \( I_{\text{bulb 1}} = \) [ ] A
- \( I_{\text{bulb 2}} = \) [ ] A
- \( I_{\text{bulb 3}} = \) [ ] A

(b) Find the resistance of each bulb.
- \( R_{\text{bulb 1}} = \) [ ] \(\Omega\)
- \( R_{\text{bulb 2}} = \) [ ] \(\Omega\)
- \( R_{\text{bulb 3}} = \) [ ] \(\Omega\)

(c) What is the total resistance of the combination of the three lightbulbs?
- [ ] \(\Omega\)
