Capacitors in Combination: Five Capacitors Are Connected Across a Potential

Multiple Choice

Capacitors in combination: Five capacitors are connected across a potential difference V_ab as shown in the figure. Because of the dielectrics used, each capacitor will break down if the potential across it exceeds 30.0 V. The largest that V_ab can be without damaging any of the capacitors is closest to

A) 6.0 V.
B) 30 V.
C) 64 V.
D) 150 V.
E) 580 V.
