Step 1

If R ohm corresponds to the load of the mobile phone during smooth run and i(t) A is the corresponding current, then the power requirement by the mobile phone during smooth run can be expressed as

Step 2

In this present case, the power requirement for smooth run is given as

Step 3

Equating equation (1) and (2), the current required f...
