Community Circuit ChallengeVersion en ligne Safe, solar-ready circuits quiz par Nhlanhla Saohatsi 1 What is the unit of electric current? a Ohm (Ω) b Volt (V) c Watt (W) d Ampere (A) 2 In a series circuit, what happens to the current across all components? a It depends on the component b It is the same through all components c It varies with time d It doubles at each component 3 Which device stores electrical energy chemically for later use? a Dishwasher b Inductor c Battery d Capacitor 4 Which device helps protect a circuit from overload in homes? a Transformer b Circuit breaker c Light switch d Fusible link 5 In a simple solar charging circuit, which component prevents reverse current into the panel? a Thermistor b Fuse c Blocking diode d LED indicator 6 If three identical bulbs are in parallel and one goes out, what happens to the others? a All brighten b The remaining bulbs stay at the same brightness c Current halves for others d All go out immediately 7 State Ohm's Law. a E = mc^2 b V = I / R c P = V × I d V = I × R 8 Two 10 Ω resistors in parallel give a total resistance of? a 15 Ω b 5 Ω c 10 Ω d 20 Ω 9 Why is safe battery storage important during load shedding? a To trigger more outages b To save water c To prevent short circuits and fires d To increase brightness 10 Why should a fuse be rated slightly above normal current? a To waste energy b To allow normal operation but protect during overload c To burn out faster d To limit voltage Feedback 1 Current is measured in amperes (A). Voltage is V, power is W. 2 In series, current is the same everywhere; voltage divides. 3 Batteries store chemical energy that converts to electrical energy. 4 Circuit breakers interrupt current during overload to prevent damage. 5 A blocking diode prevents current from flowing back into the solar panel. 6 In parallel, one bulb failing doesn’t affect others' brightness. 7 Ohm's Law relates voltage, current, and resistance: V = I R. 8 R_total = (1/10 + 1/10)^-1 = 5 Ω. 9 Proper storage reduces risk of overheating, fires and faults. 10 A fuse should carry normal current but blow on overload to protect wiring.

Vous pouvez intégrer le jeu dans un LMS compatible avec LTI 1.1 ou LTI 1.3 comme Canvas, Moodle ou Blackboard. Les scores seront ainsi automatiquement enregistrés dans le carnet de notes de la plateforme.
