In a CRT, electrons leave the filament as the current through the filament heats it upt. An anode then attracts the free electrons. According to Newton's second law of motion, the beam of electrons that emerges from the anode aperture will do this. a. Decelerate until they reach the fluorescent screen. b. Continue accelerating toward the flourescent screen. c. Spontaneoulsy decay into photons. d. Move at a constant speed toward the fluorescent screen.
3) A power supply is used to pass a current of 1 A at 6 V through a mass of copper of 255 grams for 3 minutes. During this time the mass of copper is observed to rise by 10° C. (co-0.093 cal/g°C) (Lab 10, Joule Heat). a) calculate the electrical energy in J expended by the circuit b) calculate the heat energy delivered to the Cu in calories c) calculate the ratio of answer a) to that of b) d) calc. the percentage difference in c). Use a theoretical value of 4,18 J/cal. %3D

5. In the lecture, I described Joule's use of an electric generator to heat a mass of water. Instead of a generator connected to a resistor, let there be a 12V battery connected to a 30 resistor. a) How much current will run through the circuit? b) If the heat generated by an electric circuit is given by: P = I²R how long would it take to raise 1 gallon of water by 1 degree celsius? (FYI, amps squared multiplied by ohms reduces to the units joules/second)
1) Forgetting the fact that it would be difficult to detect, if you turn on any electrical device in your car (such as air conditioner blower, headlights, or even the radio) then additional gasoline is burned by the engine. This statement is a) always true. b) true only if the car's engine is running while the electrical device is on. c) true only if the car's engine is stopped while the electrical device is on. d) never true. The energy for electrical devices in your automobile has nothing to do with the amount of gasoline your engine burns f) true in conventional cars, but not in hybrid electric cars.
