Basic Electronics

Electronics is the science and technology concerned with regulating flow of:

• Heat
• Electricity
• Water
• Power

Electricity is: 

• Flowing electrons
• Still electrons
• voltage x wattage
• amps x watts

Choose the true statement below concerning DC currents:

• DC stands for Direct Computing and electrons flow in multiple pathways
• DC stands for direct current and electrons flow in multiple directions
• DC stands for direct current and the electrons do not flow
• DC stands for direct current and the electrons flow in only one direction

The symbol for voltage is: 

• Vo
• V
• W
• Amp

Current is measured in:

• Ohms
• Voltage
• Amperes
• Watts

An expression for the overall power in a circuit is: 

• watts
• voltage
• current
• resistance

If you have three 1.5V batteries in series, what would be total voltage be? 

• 3.4 V
• 4.5 V
• 1.5 V
• 3 V

 An AA battery holder with 6 cells provides how many total volts?

• 1.5V
• 6V
• 9V
• 3V

A tool that measures voltage, current, resistance, and continuity is called a:

• voltmeter
• resistor
• multimeter
• screwdriver

Continuity measures:

• The voltage between two points.
• The resistance between two points.
• The wattage between two points.
• Whether or not there is a current between two points.
