Q: What is the effect on the total resistance when more resistors are added in parallel to a circuit?
Solution: Adding more resistors in parallel decreases the total resistance of the circuit.
Steps: 5
Step 1: Understand what a resistor is. A resistor is a component that resists the flow of electric current.
Step 2: Know what 'parallel' means. In a parallel circuit, all the resistors are connected across the same two points.
Step 3: Remember that in a parallel circuit, the current can flow through multiple paths. This means that adding more resistors gives more paths for the current to flow.
Step 4: Realize that when you add more resistors in parallel, the total resistance decreases. This is because the current can split and take different paths, making it easier for the electricity to flow.
Step 5: Conclude that adding resistors in parallel lowers the total resistance of the circuit.
