What happens when the switch is closed? When the switch is closed, nothing will change since (a) and (b) are still at same potential The diagram below shows a balanced Wheatstone Bridge circuit with four resistors P,Q,R and S. a) Explain what is meant by a balanced Wheatstone Bridge circuit. b) After a period of use the pd across the battery in the circuit reases to half of its original value. Use thevolt lab power supply The Wheatstone Bridge1shown in Figureis a cleverresistor con guration that precisely measures small changes in resistanceWhile it was invented circa (people have beenInteresting historical side note: Wheatstone didn’t actually invent this circuit Before: Potential at (a) isV, but so is potential at (b) because equal The Wheatstone bridge circuit above is usually operated by adjusting the variable resistor R3until no current flows in the ammeter. Construct the Wheatstone bridge shown in FigureUse resistor values Ra k, Rck, and Rsk Use a ade resistance box for Rb and a DC power supply Group Problem Solution: Wheatstone Bridge A circuit consists of two resistors with resistances R=! and R=!, a variable resistor, the resistance R var of which can be adjusted, a resistor of unknown value R u, and volt battery connected as shown in the figure. The changes in resistance of the strain gages are most easily measured by a Wheatstone bridge Determines the change in resistance by comparison Lab Work. Explain what effect this will have on the reading on the voltmeter You can use equation (3) by solving for the unknown resistor R4 obtaining R4 = (4) R2 R1 R3 Laboratory Exercise PART A: Pick three different fixed resistors in thekW range and combine with akW variable resistor (rheostat or potentiometer) and build a Wheatstone bridge circuit on your circuit board. Circuit Problem (1) ÎThe light bulbs in the circuit are identical. Before: Potential at (a) isV, but so is potential at (b) because equal resistance dividesV in half. What happens when the switch is closed? When R var is adjusted toohms, there is zero current through the Circuit Problem (1) ÎThe light bulbs in the circuit are identical.
