Unformatted text preview: A circuit contains six 240­Ω lamps (60­W bulbs) and a 10.0­Ω heater connected in parallel. The voltage across the circuit is 120V. What is the current in the circuit… when four lamps are turned on? when all lamps are on? when six lamps and the heater are operating? Answers Answers a) 2A b) 3A c) 15A ** **Note that the current changes so drastically when the 10.0 Ω heater is on because it’s the path of least resistance (how poetic)…more coulombs can move through the circuit every second (C/s...
