C.

Current that flows back and forth in direction.

As its name implies, alternating current will flow back and

forth in direction of flow at timed intervals. (Page 7, para

2.b.(1)).

8.

B.

3 amperes.

Ohm's Law allows you to determine the amount of amperage or

current in a circuit by equation I = E/R or 3 ohms. (Page 9,

para b.).

9.

C.

8 ohms.

Ohm's Law allows you to determine the amount of resistance in a

circuit by equation R = E/I or 8 ohms. (Page 9, para c.).

10.

C.

12 volts.

Ohm's Law allows you to determine the amount of voltage in a

circuit by equation E = I x R or 12 volts. (Page 9, para a.).

11.

B.

15 amperes.

Ohm's Law allows you to determine the amount of amperage in a

circuit by equation I = E/R = 15 amperes. (Page 9, para b.).

12.

D.

13.3 ohms.

Ohm's Law allows you to determine the amount of resistance in a

circuit by equation R = E/I. (Page 9, para c.).

13.

D.

24 volts.

Ohm's law allows you to determine the amount of voltage in a

circuit by equation E = I x R or 24 volts. (Page 9, para a.).

14.

C.

Two or more paths for current to flow.

A parallel circuit consists of two or more resister units

(electrically operated components in separate branches). [Page

11, para b.(2) ].
