Question 19
Materials: three resistors (100 Ω, 200 Ω, 300 Ω), a 9 V battery and battery clip, connecting wires, multimeter, breadboard (optional).
The 100 Ω, 200 Ω and 300 Ω resistors are in series across the 9 V battery; total resistance and current have been measured with a multimeter. Given the resistance of the circuit that you have already measured and the voltage of the battery, calculate the current flow using Ohm’s Law. Compare your calculated result with the measurement you made with your multimeter.
