Challenge Problems
Push your limits with advanced challenges
In a circuit, if 30 Coulombs of charge flow over 10 seconds, calculate the current. Then determine how many Coulombs would flow in 60 seconds at this constant current.
💡 Hint: Use I = Q/t to find the current, then multiply by time to find charge.
You have a circuit running at 5 Amperes. If the current is halved, what will be the new current and how would this affect the overall system performance?
💡 Hint: Consider how current relates to power and current consumption in appliances.
