The total number of lamps is mathematically given as

N=24

What is the total number of lamps?

Question Parameters:

How many 60-watt lamps could be connected in parallel on a 15-amp, 120-volt

Generally, the equation for the Power  is mathematically given as

P=IV

Therefore

I=P/v

I=60/120

I=0.5A

Since the system does not exceed 80% of the rating

NI=I'(0.8)

N=15*0.8/0.5

N=24

In conclusion, the total number of lamps is

N=24
