Passage one
The circuit element used to model the current-resisting behavior of a material is the ① . It is the simplest ② element. George Simon Ohm is credited with formulating the ③ relationship for a resistor based on experiments performed in 1826. This relationship is known as Ohm's Law. Ohm's Law states that the voltage across a resistor is ④ the current flowing through the resistor. The constant of proportionality is the resistance value of t
