JEE Main 4 April 2026, Shift 2, Physics Q37

Question 37 of 75 in this shift, Physics question 12 of 25, Section A.

From the circuit given below, the capacitance between terminals AA and BB shown in the circuit is ________ μ\muF. (take C1=C2=C3=1 μC_1=C_2=C_3=1\ \muF and C4=2 μC_4=2\ \muF.)

The figure, in words

Capacitor network between terminals A and B: C1, C2, C3 in series along the main line from A to B; a wire runs over the top from the node at A-side of C1 to the node between C2 and C3; C4 is connected below, between the node between C1 and C2 and the node at the B end.
