Please Help me solve the question!!
The ideal battery in Figure (a) has emf = 7.0 V. Plot 1 in Figure (b) gives the electric potential difference V that can appear across resistor 1 of the circuit versus the current i in that resistor. The scale of the V axis is set by Vs = 20.3 V, and the scale of the i axis is set by is = 3.34 mA. Plots 2 and 3 are similar plots for resistors 2 and 3, respectively. What is the current in resistor 2? E R$ R₁ (a) R₂ M V (V) Z V₂ 0 i (mA) (b)
