Lesson on Electricity and Magnetism

A string of lights is lit.  They are part of a series circuit.  One of the bulbs is removed.  The rest of the lights will

• go out

• stay lit

• get brighter

• get dimmer

Which of the following represents Ohm’s law?

• I = V / R

• V = I x R

• R = V x I

• V = I / R

What is part C considered in the circuit?

• power source

• conductor

• load/resistor

The picture shows an electrical circuit. This circuit is a series circuit because:

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current has more than one path to flow through

​ ​ (a)   is the best electrical conductor

• Copper Penny

• Plastic Tubing

• Glass Rod

• Cotton String

Electrons always travel from ​ (a)   objects to (b)   objects.

• negative

• positive

• neutral
