Q1. How many 95W light bulbs can you use in a 120V circuit without tripping a 17A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each light bulb is V.)

Q2. The electric field 5.0 cm from a very long charged wire is 3000 N/C and directed toward the wire. What is the sign of the charge on the wire? What is the linear charge density λ on the wire? What is the charge Q on a 2.0 cm long segmented of the wire?
