Challenge Problems
Push your limits with challenges.
Question 1
Design a circuit using a 12 V battery with two resistors in series of 220 Ξ© and 330 Ξ©. Calculate the total current.
π‘ Hint: Add the resistances first before applying Ohm's Law.
Question 2
You have two parallel resistors of 150 Ξ© and 450 Ξ© connected to a 9 V supply. Calculate the individual currents and the total current.
π‘ Hint: First find the current through each resistor individually, then sum them.
