Questions & Step-by-Step Solutions
What happens to the total resistance in a circuit when more resistors are added in series?
Step 1: Understand what a series circuit is. In a series circuit, all components are connected one after another in a single path.
Step 2: Know what a resistor is. A resistor is a component that resists the flow of electric current.
Step 3: Remember that in a series circuit, the total resistance is the sum of all individual resistances.
Step 4: If you add one resistor, you add its resistance to the total. For example, if you have two resistors of 2 ohms each, the total resistance is 2 + 2 = 4 ohms.
Step 5: If you keep adding more resistors, you keep adding their resistances to the total. So, if you add a third resistor of 3 ohms, the total resistance becomes 4 + 3 = 7 ohms.
Step 6: Conclude that as you add more resistors in series, the total resistance keeps increasing.
