When an electric cell is in use, .... Relation holds good.

Answer»

`EPSILON = V - Ir `
`epsilon = V + Ir`
`epsilon = V `
`epsilon = V + IR `

Solution :`epsilon = V + Ir`
When CURRENT flows AWAY from positive terminal of the cell, it gets discharged and so its tenninal voltage is,
V = `epsilon - Ir `
`THEREFORE epsilon = V + Ir `
