Question

The EMF of a cell is 10 V and its internal resistance is 2 ohm. The cell is connected to a resistor
of 8 ohm. Calculate the amount of heat in Joule that will be produced in the resistor in 60 seconds.​

Answer 1

From the ohm's law the total current can be calculated from the formula I=V/R. =1.25A. Hence, the current through the battery is 1.25 amperes.

Answer 2

Explanation:

from the ohm's law the total current can be calculated from the formula I= V/R.= 1.25A. hence the current through the battery is 1.25 amperes
