Design a circuit using a 12 V battery with two resistors in series of 220 Ω and 330 Ω. Calculate the total current.
💡 Hint: Add the resistances first before applying Ohm's Law.
You have two parallel resistors of 150 Ω and 450 Ω connected to a 9 V supply. Calculate the individual currents and the total current.
💡 Hint: First find the current through each resistor individually, then sum them.
