Given :
Reem took a wire of length 10 cm. Her friend Nain took a wire of 5 cm of the same material and thickness both of them connected with wires as shown in the circuit given in figure. The current flowing in both the circuits is the same.
To Find :
Will the heat produced in both the cases be equal.
Solution :
Heat released is given by :
H = i²Rt
Here, R is resistance and is given by :
So,
Now, in the question every thing is constant except for the length of the wire and from above equation heat is directly proportional to the length of the wire.
So, heat produced by Reem's wire is more than Nain one.
Hence, this is the required solution.

Answer:
Explanation:
Given that,
Electric Field is
E = 650 N/C
The potential at x1 = 3 is
V1 = 1700V
What is the potential at x2 = 1
V2 =?
Electric potential is given as
V = Ed
Then,
E = V/d
Therefore, the electric field is gradient of the potential and the position.
So,
E = —∆V / ∆x
E = — (V2 — V1) / (x2 — x1)
E = —(V2—1700) / (1—3)
650 = — ( V2—1700) / -2
650 × -2 = —V2 + 1700
-1300 = -V2 + 1700
V2 = 1700+1300
V2 = 3000 V
