What is the effect on the total resistance in a circuit when more resistors are added in series?
Correct Answer: Total resistance increases.
Step 1: Understand what a resistor is. A resistor is a component that resists the flow of electric current.
Step 2: Know what 'in series' means. When resistors are in series, they are connected one after another in a single path for the current to flow.
Step 3: Remember that total resistance is calculated by adding the resistance values of each resistor together.
Step 4: If you have one resistor with a resistance of 2 ohms and add another resistor with 3 ohms in series, the total resistance becomes 2 + 3 = 5 ohms.
Step 5: If you keep adding more resistors, you keep adding their resistance values to the total.
Step 6: Therefore, the more resistors you add in series, the higher the total resistance will be.
