CHAPTER NO. 01 : ELECTRICITY
ANSWERS TO PROBLEMS
Section 1-4 The Coulomb Unit of Electric Charge

1. +Q = 5 C

2. –Q = 3 C

3. +Q = 2 C

4. +Q = 15 C

5. –Q = 6 C

Section 1-5 The Volt Unit of Potential Difference

6. V = 8 V

7. V = 6 V

8. V = 12 V

9. V = 1.25 V

10. 15 J

Section 1-6 Charge in Motion is Current

11. I = 4 A

12. I = 10 A

13. I = 500 mA

14. I = 20 A

15. I = 10 A

16. Q = 7.5 C

17. Q = 1C
18. Q = 4 mC

,Section 1-7 Resistance is Opposition to Current



19. (a.) R = 1 kΩ

(b.) R = 100 Ω

(c.) R = 10 Ω

(d.) R = 1 Ω

20. (a.) R = 500 Ω

(b.) R = 250 Ω

(c.) R = 120 Ω

(d.) R = 4 Ω

21. (a.) G = 5 mS

(b.) G = 10 mS

(c.) G = 20 mS

(d.) G = 40 mS

22. (a.) G = 1 S

(b.) G = 100 µS

25. First, determine the charge, Q, in Coulombs.

Q = 6.25 × 1015 electrons × #.%& × !7#$ +,+-./012/" = 0.001 C

4 7.77! "
Therefore, I = : = !7 2
= 0.0001 A or 100 µA

!
26. At 25° C, G = !7 Ω = 0.1 S. At 100° C, G = 0.1 × 0.1 S = 0.01 S.

!
Therefore, R = 7.7! < = 100 Ω at 100° C.
