Question

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 $\Omega$ 2.00 $\Omega$ b a 6.12 $\Omega$ 7.32 V (a) What is the current (in A) in the 2.00 $\Omega$ resistor? (Enter the magnitude.) 1.54 x You may have found the current in the lower branch of the circuit (the branch with point a). The question is asking for the equation through the middle branch (with the 2.00 $\Omega$ resistor). Check which variable in your equations corresponds to this current. A (b) What is the potential difference (in V) between points a and b, that is, $\Delta V = V_b - V_a$? -12.0 X Remember that $V_b - V_a$ 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 sigh rules when finding potential differences along this path. V

Remember that $V_b - V_a$ 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 sigh
rules when finding potential differences along this path. V
