series with the circuit
2. What will happen to the current in a circuit if the resistance is doubled: Cur-
rent will be halved
3. How do you measure voltage in a circuit: Meter must be parallel with volt being
measured
4. What is the outermost shell of an atom called: Valence shell
5. The Nucleus of an atom contains what: Neutrons and protons
6. Whats the E symbol represent in ohms law: Voltage
7. What happens to the total resistance in a wire if the length is doubled: Re-
sistance is doubled
8. If an atom has only one electron in its valence shell ?: Atom will act
as a good conductor
9. Unlike charges ?: Attract
10. A neutral atom has ?: equal number protons and electrons
11. What is the name of the unit measuring current: amperes
12. Describe current flow: Uniform movement of electrons from negative to posi-
tive
13. What is the unit that measures the quantity of electrons passing a given
point: Coulomb
14. Name the unit used in measuring the potential difference across two points
in a circuit: Volt
15. What is the unit to measure opposite to current flow: Ohms
16. What happens to resistance in a wire, if its width is increased four times-
: Resistance is 1/4
17. What does the designation DPDTNO switch represent: Double-pole, Dou-
ble-Throw, Normally Open switch
18. refer to the moveable contacts on a switch: Poles
19. Contact wear is always on DC switches than AC switches: greater
20. Describe maintained contact switch action: When the switch is actuated
once, contacts close an remain close
