Electricity Basics

------ is the unit that measures the pressure or force that pushes the flow of electrons forward through a conductor.

• Wattage

• Voltage

• Amperes

• Ohm

A material in which electrons are able to move easily is called:

• an insulator.

• a conductor

What kind of circuit is this?

• Series

• Consecutive

• Parallel

• Training

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit

• series circuit

• parallel circuit

• open circuit

A series circuit has ____ path(s) that the electric current can take. 

• One

• Two 

• Three 

• Four

Does this statement best describe a parallel or a series circuit.
 
When more light bulbs are added they all remain bright. 

• Parallel circuit

• Series circuit

As the resistance of a circuit increases, the current will

• increase

• decrease

• stay the same

A resistor

• Is the same as resistance

• Is connected to a circuit in parallel

• Is used in a circuit to control the amount of current

• Is not measured in ohms

Look at this circuit - which bulbs will be lit?

• no Bulbs

• only Bulb B

• only Bulb A

• both Bulbs

Why is there a plastic coating around a metal wire?

• so it looks nice

• to insulate electricity

• to keep the wire warm

• to conduct electricity
