Condition for wheatstone bridge
WebThe Wheatstone bridge is in the balanced bridge condition when the output voltage (V OUT) between terminals A and B is equal to zero. V OUT = 0 V. When the bridge is balanced, the voltages across R 1 and R 2 are equal (V 1 = V 2 ) and the voltages across R 3 and R 4 are equal (V 3 = V 4 ). Therefore, the voltage ratios can be written as: WebWheatstone bridge is used to measure the value of unknown resistance. It uses voltage measurement to know the importance of resistance. This bridge is used in multiple compression and tension-based devices like fluid or air pressure sensors, strain gauges, etc. A robust electrical circuit can calculate the resistance effectively.

WebAboutTranscript. Wheatstone bridge is a special circuit consisting of 5 resistors. When the resistances in the adjacent arms have the same ratio, no current flows through the … WebWheatstone Bridge. The Wheatstone bridge is a circuit with two series-parallel resistor arrangements, connected with the ground and voltage supply terminal. It produces zero voltage difference between the two parallel branches in a balanced state. Wheatstone bridge is used to measure the unknown resistance in a bridge circuit.
WebExample: In a Wheatstone's bridge, three resistances P,Q and R are connected in three arms and the fourth arm is formed by two resistances S 1 and S 2 connected in parallel. Find the condition for the bridge to be balanced.
