Electricity

Electricity is a form of energy involving the flow of atoms.

• True

• False

In a circuit diagram, this symbol represents a

• switch

• multimeter

• battery

• globe

What is used to measure electric current?

• Voltmeter

• Ammeter

• Wattmeter

• pH meter

What type of circuit is this?

• Series

• Parallel

• Simple

Why are Christmas lights wired in parallel?

• It is cheaper to make

• You can make longer strands

• It uses less electricity

• If a light breaks, the others keep working

If the current in an electrical circuit is constant, what will happen to the voltage if the resistance is increased?

• Voltage will increase

• Voltage will decrease

• Voltage will stay the same

If you increase the voltage across a resistor, what will happen to the current?

• Current will increase

• Current will decrease

• Current will stay the same

If you increase the size of the resistor and keep the voltage the same, what will happen to the current?

• Current will increase

• Current will decrease

• Current will stay the same

Electric current is defined as

• detect electric current

• negative terminal to positive terminal

• positive terminal to negative terminal

• the flow rate of electric charges through a conductor

Electricity that flows in a closed path is called a

• path
• current
• circuit
