Push your limits with advanced challenges

Challenge 1 Hard

A complex circuit has three resistors in series: R1 = 100Ω, R2 = 150Ω, and R3 = 50Ω connected to a 40V power supply. Calculate the total current in the circuit.

💡 Hint: Determine total resistance first before finding the current.

Challenge 2 Hard

A circuit has a 24V supply connected to a 12Ω resistor. Calculate how much power is consumed by the resistor.

💡 Hint: Use Ohm's Law to find current, then calculate power.
