Q.1 Potential difference between A and B and B and C in steady state ? Detailed Solution Please
pd between A and B is 25V and pd between B and C is 75V because dc current gets blocked in rc circuit when circuit reaches steady state ie capacitors are fully charged in the given circuit no current can flow
Since the two capacitors are in parallel and also the two capacitors are in parallel, the circuit can be simplified by taking equivalent capacitance i.e, and respectively. Now in the steady state, the voltage across all the parallel branches will be 100V. And in the second parallel branch of the simplified circuit, 100V will be distributed between the and according to the relation: Thus, , i.e, V1= 25V and V2 = 75VHence, Vab = 25V and Vbc = 75V.
