Question
1. In the Coulomb's Law experiment, the spheres were charged by touching with a a. voltmeter b. ground probe charging probe d. ammeter 2. The charges carried by the spheres above were proportional to the ( potential b.current c.resistanced.temperature 3. By mapping the equipotential lines, you can draw a. the charge b. the electric field lines c. nothing d)the magnetic field line 4. In which of the following experiments a galvanometer was NOT used? mapping of the electric field the Wheatstone bridge method b. study of a source of emf and terminal voltage )ca a. c. pacitance and capacitors 5. When a dielectric was inserted between the plates of the capacitor, the capacitance increased b. decreased c. was zero d. wasn't affected 6. When verifying Ohm's law, you found that the clectric current was a function of a capacitance voltage cmilliamps d. time When you verified the heating effect of an electric current, every 60 seconds, you measured 7. temperature b. time c. resistance d. current 8. Which experiment verified conservation of energy? b. d. the heating effect of an electric current the Wheatstone bridge method a. Ohm's law capacitance and capacitors 9. Fig. 1 is a Wheatstone bridge circuit Fig. I is a Wheatstone bridge circuit. No current flows through the galvanometer. You find Rx is 9. b.sa c, 25 d. 144 a.1 -0.00142+ 00000s 1 10r-02 3.008-0 Rx 12 60 Veltage [V Fig. 2 Fig. 1Explanation / Answer
1.(c) charging probe
2. (a) POTENTIAL
3.(b) The magnetic field line
4.(c) Capacitance and capacitors
5.(a) increased
6.(b) voltage
7.(a) temperature
8.(b) Capacitance and capacitors
9.(c) 25 ohm
Rx/5 = 60/12 gives Rx = 25ohms
