Question

1. Read the following circuit I-top and circuit II below it and answer the question: In the given circuit I and II shown below the total potential difference across a combination of a resistor in circuit I is a V1 + V2 + V3 b VI - V2 + V2 c V, + V2 d. None of these ​

Answer 1

Answer:

(a)As all the resistances are in parallel the voltage across each of them will be same =12V
