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

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

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

• 3 kΩ

• 10 kΩ

• 13 kΩ

• 18 kΩ

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

The equivalent resistance in this circuit is 

• 100 ohms
• 450 ohms
• 400 ohms
• 30 ohms
