Q: What is the effect on the total resistance when more resistors are added in series to a circuit?
Solution: In series, the total resistance increases as more resistors are added.
Steps: 6
Step 1: Understand what a resistor is. A resistor is a component that resists the flow of electric current.
Step 2: Know what 'series' means. In a series circuit, components are connected one after another in a single path.
Step 3: Remember that each resistor adds its own resistance to the circuit.
Step 4: When you add more resistors in series, you are increasing the total resistance because the current has to pass through each resistor one after the other.
Step 5: The total resistance in a series circuit is the sum of all individual resistances. So, if you have R1, R2, and R3, the total resistance (R_total) is R1 + R2 + R3.
Step 6: Conclude that as you add more resistors, the total resistance keeps increasing.
