Explanation / Answer

11 .A body that has relatively few free electrons and offers comparatively great resistance to the movement of free electrons is a/an

Insulator.

12. The relationship between a cathode and an anode involves

B. electrons.

They attracted to anode and protons which attract to cathode

13. If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V, the current flowing through the circuit is

From Ohms Law,
Volatage = current * Resistance
I = V/R = 60/12
I = 5 A

14. When all parts of a circuit are composed of conducting materials, the circuit is said to be

C. closed.

15. The function of a capacitor in an electric circuit is to
C. store electric charges.

16. The ability to regulate the amount of charge flowing in a circuit is
A. resistance.

you can even use specific term like Variable resistor.
