Challenge Problems
Push your limits with challenges.
Question 1
A Wheatstone Bridge consists of R1 = 120Ω, R2 = 75Ω, and R3 = 30Ω. Calculate the value of R4 when balanced and explain the implications of this balance for resistance measurements.
💡 Hint: Use cross multiplication for the ratio.
Question 2
In an experiment, a Wheatstone Bridge's known resistors are adjusted, yielding a balanced state when R1 = 10Ω and R2 = 30Ω along with R3 being unknown. Determine R4 if R3 is found to be 15Ω and analyze its significance in a practical setting.
💡 Hint: Think about how the ratio reflects the respective resistance values.
