The figure shows a circuit of four resistors that are connected toa larger circuit. The graph below the circuit shows the electricpotential V(x) as a function of position x alongthe lower branch of the circuit, through resistor 4; the potentialVA is 11.6 V. The graph above the circuit showsthe electric potential V(x) versus position x along theupper branch of the circuit, through resistors 1, 2, and 3; thepotential differences are ΔVB = 1.72 V andΔVC = 5.72 V. Resistor 3 has a resistanceof 214 Ω. What is the resistance of resistor 1?
