three resistors with resistances 250ohms, 500ohms, 1kohms are connected in series. a 6v battery is connected at each end of the combination. calculate the potential difference between the ends of the 250ohms resistor​

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.
