The figure below shows a circuit consisting of three ideal batteries and four resistors. The batteries have emfs &₁ = 2.0 V and E2 E3 = 4.0 V. The resistances are R₁ = 1.0 and R₂ = 2.0. R₁ +18, R₁ a R₁ www Est R₂ + Eq R₁ (a) What is the current (magnitude and direction) in each battery? (b) What is the potential difference V₁ - V₁ between the points a and b indicated in the figure? (c) Check your results by checking the sum of the currents at the node you did not use for your node equations and the voltages in a loop you did not use. (d) Check your results by choosing ground at one point in the circuit as your V=0 reference and finding each unique voltage in the circuit and labeling the circuit with those voltages.
