Basic Electrical Concepts

The unit for resistance is       .

• Ampere
• Amp
• Ohm
• Ohmere

Thermal energy produces 

• Direct Current
• Random electron motion
• Directed electron motion
• Voltage

Conventional current flow is defined as the 

• flow of electrons "charge" from positive to negative
• flow of electrons "charge" from negative to positive
• flow of electrons "charge" from north to south
• up hill

The unit for resistance is       .

• Ampere
• Amp
• Ohm
• Ohmere

The unit of measurement for current is

• Volt

• Ampere

• Joule

• Ohm

If the 4th band on a 4 band resistor is gold this means      .

• the tolerance is plus or minus 5% of the value of the resistor.
• the tolerance is plus or minus 10% of the value of the resistor.
• You add 9 zeros to the first 3 numbers.
• you've struck it rich.

An example of an insulator is     .

• Copper
• Capacitor
• Resistor
• Rubber

Voltage is 

• the force that moves electrons
• the unit of measure for power
• the unit of measure for resistance 
• power multiplied by current

In a circuit , the actual electron flow is

• from the positive terminal of a voltage source to negative terminal

• from the negative terminal of a voltage source to the positive terminal

• absence in resistance

• from a battery to a lamp

The electron has a 

• positive charge
• negative  charge
• neutral charge 
• all of the above
