25. The electric potential of a metallic sphere is 10V and that of another metallic sp
-10V. If a wire of Resistance 2 ohm is connected between the two spheres, how
current will flow through it just after connection?
(1)0 A (2) SA (3) 10 A (4) 20 A

After connecting the spheres
Potential differences between them will be
V1-V2 = 10 - (-10) = 20 V
Resistance R =2 ohm
Therefore cure flows,
I = V/R = 20/2 = 10 A
Option (3) is correct
