The document appears to describe a circuit diagram with components including a switch S, resistances Ri and R, and capacitors C. If switch S is closed, the current in resistor Ri will increase. This is because closing the switch places resistances R2 and R3 in parallel, reducing the total equivalent resistance seen by the battery. A lower total resistance causes the current through the battery to increase.

A) 150 04: In the circuit shown, if the switch S is closed, the current in Ri A) will decrease B)
will increase C) will remain the same as before D) may increase or decrease depending on the
resistance R E Values of Ri, Ro and Ro must be given to answer this question. OS: Two equal
air-filled capacitors C, maintained at constant potential B) 50 li thrm te battery as shown in the
figure, A slab of dielectrio ting
Solution
switch is closed then R2 and R3 will be in parallel.
and their equivalent, R < R2 and R < R3.
initially, R_eq = R1 + R2
now R_eq' = R1 + R
total resistance of circuit has decreased so current will be greater through battery,
