In a Wheatstone bridge, if the ratio of resistances R1 to R2 is equal to the rat

In a Wheatstone bridge, if the ratio of resistances R1 to R2 is equal to the ratio of R3 to R4, what can be concluded?

In a Wheatstone bridge, if the ratio of resistances R1 to R2 is equal to the ratio of R3 to R4, what can be concluded?

Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown resistances by balancing two legs of a bridge circuit.
Step 2: Identify the resistances in the Wheatstone bridge. There are four resistors: R1, R2, R3, and R4.
Step 3: Know the condition for balance in a Wheatstone bridge. The bridge is balanced when the ratio of the resistances in one leg equals the ratio in the other leg.
Step 4: Write the condition for balance mathematically. This is expressed as R1/R2 = R3/R4.
Step 5: Conclude what happens when the bridge is balanced. When R1/R2 equals R3/R4, it means that no current flows through the galvanometer, indicating a balanced state.
