Listen An emf is connected to the circuit below. It has a voltage, E, and an internal resistance, r. R, IN Rm a MM RZ a. Determine Vab and the current through Rm. b. What is the effective resistance of this circuit? c. Solve for the current flowing out of the emf. d. Suppose Rm was replaced with a capacitor and an open switch. Immediately after the switch has been closed, would current flow between points a and b? e. Suppose Rm was replaced with a capacitor and an open switch. After a long time, would current flow between points a and b
