1

Which of the following is the preferred method for splicing wires?

57% Answer Correctly

soldering

wire crimps

screw-on connectors

wrap in small gauge wire


Solution

Splicing is permanently joining two wires together. Splicing can be done with screw-on connectors or wire crimps but the preferred method for splicing is soldering. Soldering takes the most effort but results in a connection that is electrically and mechanically identical to the original wire.


2

Inductance is a factor in which of the following?

44% Answer Correctly

a DC circuit

determining energy stored by a capacitor

an AC circuit

batteries connected in serial


Solution

Inductance is a property of an AC circuit (or a component in an AC circuit) that quantifies resistance to changes in current. The current in an AC circuit is continuously changing and inductive reactance (the opposition to change) depends both on the inductance of the circuit or component and the rate at which the current is changing.


3

The rate of flow of electrons per unit time is which of the following?

74% Answer Correctly

resistance

current

conductance

voltage


Solution

Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.


4

The valence shell of a conductor is how full of electrons?

52% Answer Correctly

more than half full

half full

full

less than half full


Solution

Conductors are elements that allow electrons to flow freely. Their valence shell is less than half full of electrons that are able to move easily from one atom to another.


5

The ohm is a unit of measurement for:

80% Answer Correctly

energy

capacitance

power

resistance


Solution

Resistance is opposition to the flow of current and is measured in ohms (Ω). One ohm is defined as the amount of resistance that will allow one ampere of current to flow if one volt of voltage is applied. As resistance increases, current decreases as resistance and current are inversely proportional.
