Problem

When two identical batteries of internal resistance 1Ω1\Omega each are connected in series across a resistor RR , the rate of heat produced in RR is J1J_1 . When the same batteries are connected in parallel across RR , the rate is J2J_2 . If J1=2.25J2J_1 = 2.25 J_2 then the value of RR in Ω\Omega is
