Question 1

What is the total resistance of two resistors R1 and R2 connected in series?

Accepted Answer

R1 + R2

Answer

R1 * R2

Answer

1/(1/R1 + 1/R2)

Answer

R1 - R2

Question 2

What is the total resistance of two resistors R1 and R2 connected in parallel?

Accepted Answer

1/(1/R1 + 1/R2)

Answer

R1 - R2

Answer

R1 + R2

Answer

R1 * R2

Question 3

If three resistors, R1, R2, and R3, are connected in series, what is the formula for the total resistance?

Accepted Answer

R1 + R2 + R3

Answer

R1 * R2 * R3

Answer

R1 - R2 - R3

Answer

1/(1/R1 + 1/R2 + 1/R3)

Question 4

What is the equivalent resistance of three resistors R1, R2, and R3 connected in parallel?

Accepted Answer

1/(1/R1 + 1/R2 + 1/R3)

Answer

R1 * R2 * R3

Answer

(R1 + R2 + R3)/3

Answer

R1 + R2 + R3

Question 5

Which characteristic is true for resistors connected in parallel compared to those connected in series?

Accepted Answer

They have the same voltage across each resistor.

Answer

The total resistance is the sum of all resistances.

Answer

They have the same current passing through each resistor.

Answer

They cannot be used for voltage division.
