 okay so we are going to discuss now how we can take care of the situation for Wheatstone bridge in capacitors okay so draw this Wheatstone bridge of capacitor let us say this is C1, C2, C3, C4 and C5 now when C5 will become useless or when the capacity so it's like water it just goes out so it can't store anything these two point is zero this capacitor will not store any charge so effectively capacity potential of this point is equal to potential of that point relation among C1, C2, C3, C4 for that so assume if this q charge how much charge this plate will have so some of the charge this plate has no charge so this will have minus q this will have plus q this is minus q okay let's say this is q1 so this is q1 and suppose q2 charge okay this stop talking this is minus q2 this will have more charge plus q2 and this is minus q2 fine now this is one loop and this is other loop can you write down that your loop rule equation for these two so I'm going from I'm decreasing my potential so it will be minus q1 by C2 okay 1 is equal to 0 for equation now in second loop let's go from A to this point D q2 by C4 is equal to 0 so q1 by C3 is equal to C4 this is the second equation so again this is a very simple looking expression C3 by C2 is equal to C4 by C1 when that happens this capacitor you can just throw it away because it has no meaning it doesn't store any charge it's 6 I by 6 this is I by 6 by 6 and this one also becomes I by 3 okay in this loop this one that's tunnel 1 see what you get is equal to 0 so V is equal to 6 5 so equation basis is 5 by 6 this one one or two more questions like this you're showing some question right yes so whatever these two and these two minus I by 3 are is equal to 0 so V is equal to 2R by 3 times pi or V by pi 2R by 3 same answer 2R by 3 what is 6R by 7? 4R minus 5 so and this out I2R minus 2R by 3 I2 is equal to 0 so V minus 3 to the 6 this is 8 to R by 3 is equal to 0 so I2 will be equal to 3V by 8R yes this current the same as that current has to be so this current is not splitting here whatever this coming here goes like this
