Understanding Parallel Resistors

What happens to the total resistance if the number of equal resistors in parallel increases?

• It increases

• It decreases

• It remains the same

• It doubles

If two resistors, each of 6 ohms, are connected in parallel, what is their total resistance?

• 12 ohms

• 6 ohms

• 3 ohms

• 4 ohms

If you have three resistors of values 6 ohms, 6 ohms, and 6 ohms in parallel, the total resistance is:

• 6 ohms

• 2 ohms

• 0.67 ohms

• 1 ohm

What is the total resistance when three 9-ohm resistors are connected in parallel?

• 3 ohms

• 9 ohms

• 27 ohms

• 6 ohms

For four resistors of 4 ohms each in parallel, the total resistance is:

• 1 ohm

• 4 ohms

• 16 ohms

• 2 ohms

The total resistance of four 10-ohm resistors in parallel is:

• 2.5 ohms

• 10 ohms

• 40 ohms

• 5 ohms

If two resistors in parallel have resistances of 8 ohms and 8 ohms, their total resistance is:

• 4 ohms

• 8 ohms

• 16 ohms

• 2 ohms

For three resistors of 15 ohms each in parallel, the total resistance is:

• 1.67 ohms

• 5 ohms

• 15 ohms

• 2.5 ohms

If four resistors, each of 12 ohms, are connected in parallel, their total resistance is:

• 48 ohms

• 12 ohms

• 3 ohms

• 6 ohms

The formula for calculating the equivalent resistance of four resistors in parallel is:
