Challenge Problems
Push your limits with challenges.
Question 1
A series circuit has three resistors: R1 = 2Ξ©, R2 = 3Ξ©, and R3 = 5Ξ©, with an applied voltage of 12V. Calculate the total power consumed by the circuit.
π‘ Hint: Calculate total resistance first, then find current and finally power.
Question 2
If a parallel circuit contains a 10Ξ© and a 5Ξ© resistor, what is the current flowing if 20V is supplied across the circuit?
π‘ Hint: Use the formula for equivalent resistance in parallel circuits.
