JEE AdvancedPhysicsCurrent ElectricityNumerical+3 / −1
When two identical batteries of internal resistance 1 Ω\OmegaΩ each are connected in series across a resistor R, the rate of heat produced in R is J1. When the same batteries are connected in parallel across R, the rate is J2. If J1 = 2.25 J2, then the value of R in Ω\OmegaΩ is ‾\underline{\hspace{2cm}}​.
