A 110 V power line is protected by a 14A fuse. Whst is the maximum number of 500 W lamps that can be simultaneously operated in parallel on this line without "bowing" the fuse because of an excess of current?

A number of identical light bulbs are connected in parallel toa120V AC power source. Each bulb dissipates an average powerof 60W.The circuit has a fuse that burns out when thecurrent in thecircuit reaches 9.0 A. What is the maximumnumber of bulbs that canbe added in parallel without burning outthe fuse?

I know that the voltage of 120 is the RMS value, so Vrms =120V
I also know that the average power (Pav), equates to Irms^2 xR
I'm confused as to the current that is given. Should I setthis asthe maximum current? Or would I use it like a rmsvalue?
