When two identical batteries of internal resistance 1 each (having polarity in same direction) are connected in series across a resistor R, the rate of heat produced in R is P1. When the same batteries(having polarity in same direction) are connected in parallel across R, the rate is P2. If P1 = 2.25 P2 then find the value of R in ohm
