Internal Resistance: DCIR and ACIR
The formula for DCIR measurement is, DCIR = (V 0 – V 2) / (I 2 – I 0) = ΔV / ΔI There are standards set by the regulatory body, which should be followed while measuring the DCIR of a cell. These standards are set for universality and apple-to-apple comparison. I will
