The figure below shows with two batteries and three resistors. The potential difference across the batteries and the resistance of each resistor is given in the figure. 12.0 V + 4.00 0 2.00 0 + 5.82 0 7.86 V (a) What is the current (in A) in the 2.00 0 resistor? (Enter the magnitude.) 0.8 X Use Kirchhoff's junction and loop rules to find equations to solve for the unknown currents in the branches of the circuit. You will need one junction equation and two loop equations to get three equations and three unknowns. Be careful of sign rules in your equations. A (b) What is the potential difference (in V) between points a and b, that is, AV = V - Va? X Remember that V, - V, refers to the potential at the final point (point b) minus the potential at the initial point (point a). Can you choose a path in the circuit from a to b that uses the current found in part (a)? Be careful of sign rules when finding potential differences along this path. V Need Help? Read It Submit
