A cell has an emf 1.5Vwhen connected across in an external resistance ...
To calculate the current flowing through the cell, we can use Ohm's Law, which states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the resistance (R):

I = V / R

In this case, the emf (E) of the cell is 1.5V and the external resistance (R) is 2Ω. Therefore, the current flowing through the cell can be calculated as:

I = E / R
I = 1.5V / 2Ω
I = 0.75 A

So, the current flowing through the cell when connected across an external resistance of 2Ω is 0.75 amperes.
