Questions & Step-by-Step Solutions
In a Wheatstone bridge, if the resistances are 1Ω, 2Ω, 3Ω, and 6Ω, is the bridge balanced?
Steps
Concepts
Step 1: Identify the resistances in the Wheatstone bridge. They are 1Ω, 2Ω, 3Ω, and 6Ω.
Step 2: Label the resistances. Let's say R1 = 1Ω, R2 = 2Ω, R3 = 3Ω, and R4 = 6Ω.
Step 3: Check the condition for a balanced Wheatstone bridge. The bridge is balanced if R1/R2 = R3/R4.
Step 4: Calculate R1/R2. This is 1Ω / 2Ω = 1/2.
Step 5: Calculate R3/R4. This is 3Ω / 6Ω = 3/6, which simplifies to 1/2.
Step 6: Compare the two ratios. We have 1/2 (from R1/R2) and 1/2 (from R3/R4).
Step 7: Since both ratios are equal (1/2 = 1/2), the bridge is balanced.
