Question 20
Materials: three resistors (100 Ω, 200 Ω, 300 Ω), a 9 V battery and battery clip, connecting wires, multimeter, breadboard (optional).
In this series circuit, imagine replacing one of the fixed resistors with a variable resistor. How would adjusting the resistance of the variable resistor affect the total resistance and the current in the circuit?
