Question
21. [1pt]
Figs. 1 and 2 show a dielectric slab being inserted between the plates of one of two identical capacitors, capacitor 2. Select the correct answer to each of the statements below (enter I for `increases', D for `decreases', or S for `stays the same').
A. In Fig. 2, the potential difference between the plates of capacitor 2 ____ when the dielectric is inserted.
B. In Fig. 2, the charge on capacitor 2 ____ when the dielectric is inserted.
C. In Fig. 1, the capacitance of capacitor 2 ____ when the dielectric is inserted.
D. In Fig. 2, the potential energy stored in capacitor 2 ____ when the dielectric is inserted.
V. Figure 1 #1 Figure 2 V. #1 #2 #2Explanation / Answer
Capacitance increases as we insert dielectric slab
so analysing above we fing
A.S as parallel connection with constant voltage supply
B.I as capacitance increases by K and Q=0.5CV^2 and V is contant
C.I
D.I same as 2nd
