What happens to the total resistance in a parallel circuit as more resistors are added?

• The total resistance decreases.

• The total resistance increases.

• The total resistance stays the same.

• The total resistance becomes infinite.

What is the formula to calculate total resistance in a parallel circuit?

• Rt = R1 * R2 * R3 * ... * Rn

• Rt = R1 + R2 + R3 + ... + Rn

• Rt = R1 - R2 - R3 - ... - Rn

• It stays the same

• It increases

• It becomes negative

What is the formula to calculate total resistance in a series circuit?

• The total resistance in a series circuit is calculated by subtracting the individual resistances.

• The total resistance in a series circuit is calculated by adding up the individual resistances.

• The total resistance in a series circuit is calculated by multiplying the individual resistances.

• The total resistance in a series circuit is calculated by dividing the individual resistances.
