Question 1
A parallel circuit consists of two resistors: R_A = 150 Ω and R_B = 450 Ω connected to a 12 V battery. Calculate the total current and the total resistance.
💡 Hint: Break the problem down by calculating current in parts.
Question 2
If a third resistor R_C = 100 Ω is added in parallel to the previous circuit, determine the new total current and resistance.
💡 Hint: Include the new resistor's contribution to current and resistance.
