A battery of 6 V is connected to the ends of uniform wire 3 m long and of resistance 100 . The difference of potential between two points 50 cm apart on the wire is
Options
- A1 V
- B2 V
- C1.5 V
- D3 V
Correct answer
A. 1 V
Step-by-step solution
aligned & R = l ~A & 100 3 = A aligned Total resistance for 50 cm wire is aligned & R ^ = A l= 100 3 (50 10⁻² )= 50 3 ...(i) & I ~V R = 6 100 ~A ...(ii) aligned The potential difference between two points 50 cm apart is V=I R^ = 6 100 50 3 =1 ~V ...[From (i) and (ii)]
