Define Voltage? - Answer-The driving force that makes current flow in a circuit. Voltage
often represented by the letter E, is also referred to as electromotive force (emf),
difference of potential, or electrical pressure.

Define Current? - Answer-The movement, or flow, of electrons in a circuit. Current(I) is
measured in amperes.

Define Resistance? - Answer-An electrical property that opposes the flow of current
through a circuit. Resistance (R) is measured in ohms.

Define Watts? - Answer-The unit of measurement for electrical power, represented by
the letter W.

Define Amperes? - Answer-The basic unit of measurement for electrical current,
represented by the letter A.

What is a Coulomb? - Answer-A unit of electrical charge equal to 6.25x10^18 electrons
(or 6.25 quintillion electrons.) A coulomb is the common unit of quantity used for
specifying the size of a given charge.

What is an Ammeter? - Answer-An instrument for measuring electrical current.

What is an Ohmmeter? - Answer-An instrument used for measuring resistance

What is an Voltmeter? - Answer-An instrument for measuring voltage. The resistance of
the voltmeter is fixed. When the voltmeter is connected to a circuit, the current passing
through the meter will be directly proportional to the voltage at the connection points.

A Proton(+) repeals another? - Answer-Proton(+)

An Electron(-) repeals another? - Answer-Electron(-)

A Proton(+) attracts an? - Answer-Electron(-)

When no fourth band is present, the resistor tolerance is? - Answer-+ or - 20%

In a parallel circuit, the total resistance is less than the? - Answer-Smallest of the
individual resistances.

In-line ammeters are less common and must be? - Answer-Connected in series with the
circuit, which means that the circuit must be opened.
