Answer 1

Answer:

Three identical capacitors are connected in series as shown in figure, across a 12 V battery. Point P is earthed. The potential of point A and B are respectively  8V AND -4V

Explanation:

Voltage drop across each capacitor = 4 V as point P is earthed. Hence Vp = 0.

⇒ VP – VB = 4

VB = – 4 V

VA – VB = 12

VA = 12 – 4 = 8 V
