Question

The figure below shows a circuit of four resistors that are connected to a larger circuit. The graph below the circuit shows the electric potential V(x) as a function of position x along the lower branch of the circuit, through resistor 4. The graph above the circuit shows the electric potential V(x) as a function of position x along the upper branch of the circuit, through resistors 1, 2, and 3. Resistor 3 has a resistance of 70 Ohm and n = 6. What is the resistance of resistor 1? Ohm What is the resistance of resistor 2? Ohm.

Explanation / Answer

a) V across 4 is 12V V across 3 is 12-2-6 =4V current = 4/70 A R1 = 2/(4/70) = 70/2 =35 ohms b) R2 = 6/(4/70) = 105 ohms
