c) A 6 V battery B has an internal resistance of 1 2. It is connected in parallel with a 5 resistor 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 = ∞, and when R = 1.25 2. 2 ii) Using your results from (i) or otherwise, show that the parallel combination of B and R5 is equivalent to a battery of voltage Veq with internal resistance Req, and find the values of Veg and Req.
