Essential Question

1. What is the relationship between equivalent resistance and resistors on a parallel circuit?

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

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

• 3 kΩ

• 10 kΩ

• 13 kΩ

• 18 kΩ

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

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
