Using Kirchhoff's rules, find the following. (E, = 71.0 V, E2 = 62.0 V, and E, = 79.8 V.) 4.00 ka |E, |E. Ra R$ 3.00 kN 2.00 kN R (a) the current (in mA) in each resistor shown in the figure above IR2 mA mA (b) the potential difference between points c and f (Give the magnitude of your answer in volts and select the point of highest potential.) magnitude of potential difference point at higher potential --Select--- v (c) What If? If all of the resistors in the circuit were decreased in value by a factor of 1,000, would the current in each resistor simply increase by a factor of 1,000? Explain your answer.

Two resistors, R, = 2.57 2 and R, = 5.81 2, are connected in series to a battery with an EMF of 24.0 V and negligible internal resistance. Find the current I, through R1 and the potential difference V½ across R2. I = A R2 V½ = V

A battery has an emf ɛ and an internal resistance r. It is connected to an external resistor R. When R = 4.5 N the terminal potential difference is 13.01V. When R = 8.5 N the terminal potential difference is 13.71V. Find e and r. V = 3 r =
