In complex electrical networks, resistors are often connected in configurations that are neither purely series nor purely parallel. These configurations are typically or Delta (Δ) networks. To simplify such circuits and calculate total resistance or current, we use transformation techniques to convert a Star configuration into a Delta configuration, or vice versa.
