Basic Concept of Electricity and Electronics

Electricity is:

• Flowing electrons

• Still electrons

• Voltage x Wattage

• Amps x Watts

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

• Heat
• Electricity
• Water
• Power

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

• A

Current is measured in:

• Ohms
• Voltage
• Amperes
• Watts

Resistance is measured in:

• Volts

• Amps

• Ohms

• Watts

An expression for the overall power in a circuit is:

• Watts

• Voltage

• Current

• Resistance

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

• Voltmeter

• Resistor

• Multimeter

• Ammeter

Current can only flow if there is a/an

• Open circuit

• Closed circuit

• Parallel circuit

• Short circuit

An AA battery holder with 4 cells provides how many total volts?

• 1.5 V

• 6 V

• 9 V

• 3 V
