Challenge Problems
Push your limits with challenges.
Question 1
Consider a circuit where 2A enters a junction and 1.5A exits through one branch. If another branch has a total resistance of 10Ω, find the current flowing through that branch.
💡 Hint: Apply KCL to balance the currents first.
Question 2
An RC circuit consists of a 1µF capacitor charged to 10V. Calculate the time constant if a 1kΩ resistor discharges it. What is the voltage after 2 time constants?
💡 Hint: Use the discharging formula for a capacitor.
