Explanation:
It is given that,
Potential difference between the ends of a rod, V = 1.1 V
Length of the rod, l = 10 cm = 0.1 m
Area of cross section of the rod,
The resistivity of graphite,
(a) Let R is the resistance of the rod. It is given by :
So, the resistance of the rod is 0.833 ohms.
(b) Let I is the current flowing in the wire. It can be calculated using the Ohm's law as :
I = 1.32 A
(c) Let E is the electric field inside the rod. The electric field in terms of potential difference is given by :
E = 11 V/m
Hence, this is the required solution.
Electric field due to a point charge is given by formula
now due to negative charge also the magnitude of electric field will be same
only difference is the direction of field due to negative charge is radially inwards
now we can say that net field due to these two charges is given as
now it is given that distance r is very large than "d" so we can say
<em>so above is the electric field due to dipole</em>
