A wire of length `12 cm` resistance `12 Omega` and of uniform area of cross section is cut into twelve equal parts . Which are connecting to form a skelton cube A cell of emf `2V` is connected across the two diagonally opposite correct of the cube Using kirchhoff's laws of junction and loop answer the following question
The current drawn from the battery is

A

`2.5 A`

B

`2.4A`

C

`2.3A`

D

`3.4A`

Text Solution

Verified by Experts

The correct Answer is:
b
Current drawn from the battery
`I = ("e.m.f")/("resistance") = (2)/(5//6) = 2.4A`
