c)A 6 V battery B has an internal resistance of 1 2. It is connected in parallel with a 5resistor R5 and this combination is in series (and parallel) with a resistor R of RS.i) Find the voltage VR across R for the three cases, when R = 0, when R = ∞, andwhen R = 1.25 2.2 ii) Using your results from (i) or otherwise, show that the parallel combination of B andR5 is equivalent to a battery of voltage Veq with internal resistance Req, and find thevalues of Veg and Req.
