The internal resistance of a 2.1 v cell
Asked by admin @ in Physics viewed by 278 People
The internal resistance of a 2.1v cell which gives a current of 0.2 A through a resistance of 10 ohm is
Answered by admin @
use formula
r=(E/V-1)R
r=internal resistance
E=emf=V+ir
V=terminal potential
R=external resistance
put the value then get answer
