Electricity & Magnetism Review

Multiple Choice

How do you calculate current

Resistance X Voltage

Voltage X Resistance

Resistance ÷ Voltage

Voltage ÷ Resistance

Multiple Choice

How do you calculate voltage?

Current X Resistance

Resistance ÷ Current

Current ÷ Resistance

Measure it with a ruler

Multiple Choice

What is voltage measured in?

Ω (Ohms)

V (Volts)

A (Amps)

W (Watts)

Multiple Choice

What is resistance measured in?

Ω (Ohms)

V (Volts)

A (Amps)

W (Watts)

Multiple Choice

What 'flows' in a wire?

Protons

Neutrons

Atoms

Electrons

Multiple Choice

Which direction does convention current flow?

Positive to negative

Negative to positive

Negative to Negative

Positive to Positive

Multiple Choice

This is an example of a ______ circuit

Series

Parallel

Open

Dihexihedral

Multiple Choice

This is an example of a _______ circuit

open

series

parallel

square

Multiple Choice

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 is divided between the three light bulbs.

Multiple Choice

What is Resistance?

the degree to which a circuit component opposes the passage of an electric current, causing energy dissipation

How hard the energy is pushed

The amount of charges that pass by a given point per second

None of the above

Multiple Choice

How to you calculate the total resistance in a series circuit?

R1 + R2+ R3

R1 - R2 - R3

1/R1 + 1/R2 + 1/R3

R1 = R2 = R3

Multiple Choice

What is the equivalent or total resistance (R_e) across this circuit?

3 kΩ

10 kΩ

13 kΩ

18 kΩ

Multiple Choice

The equivalent resistance in this circuit is

100 ohms

450 ohms

400 ohms

30 ohms

Multiple Choice

How would the equivalent resistance be determined?

1 / Req = (1/5) + (1/8) + (1/3) Ω

120 Ω

1.5189873 Ω

1 / Req = (1/5) * (1/8) * (1/3) Ω

Multiple Choice

How do you calculate total resistance in a parallel circuit?

R1 + R2 + R3

R1 - R2 - R3

1/R1 +1/R2 + 1/R3 = 1/RT

R1 = R2 = R3

Multiple Choice

Which of the following is a material that a magnet would attract?

Plastic

Aluminum

Wood

Iron

Multiple Choice

If you place the North pole of a magnet next to the South pole of another magnet, they will:

Attract

Repel

Do nothing

Shatter

Multiple Choice

What do the lines around this magnet represent?

North Pole

South Pole

Magnetic Declination

Magnetic Field

Multiple Choice

As the distance between two magnets increases (they get farther apart), the force between them:

Increases

Decreases

Stays the Same

Multiple Choice

What will happen when these magnets are brought close together?

They will attract each other.

They will repel each other.

Both magnets will turn to the left

Both magnets will turn to the right

Multiple Choice

The strongest part of a magnet is...

the bars.

the force field.

the poles.

the middle.

Multiple Choice

What two forces are required for generators and electric motors to work?

magnetism and thermal

electricity and thermal

electricity and magnetism

magnetism and radiant
