Challenge Problems
Push your limits with challenges.
Question 1
A series circuit consists of three resistors: R1=50Ω, R2 = 150Ω, and R3 = 100Ω connected to a 12V battery. Calculate the total resistance, current through the circuit, and the voltage across each resistor.
💡 Hint: Remember to calculate R_total first before finding I and voltage drops.
Question 2
If a series circuit with a total resistance of 500Ω has a current of 0.02A, find the voltage supplied by the battery and the voltage across a resistor of 200Ω in the circuit.
💡 Hint: Use Ohm’s Law for finding the overall voltage and then for the specific voltage drop.
