How many 112 w lightbulbs can you use in a 100 v circuit, Ask an Expert

Academics

Q. How many 112 W lightbulbs can you use in a 100 V circuit without tripping a 15 A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each lightbulb is 100 V.)

Q. Find the minimum aperture diameter of a camera that can resolve detail on the ground the size of a person (2.0 m) from an SR-71 Blackbird airplane flying at an altitude of 29 km. (Assume light with a wavelength of 480 nm.)
