In the figure the resistances are R 1 = 1.0 Ω and R 2 = 2.0 Ω, and the ideal batteries have emfs ε 1 = 2.7 V, and ε 2 = ε 3 = 3.8 V. What are the (a) size and (b) direction (up or down) of the current in battery 1, the (c) size and (d) direction of the current in battery 2, and the (e) size and (f) direction of the current in battery 3?(g) What is the potential difference V a - V b?

An ideal voltmeter connected across a certain 9-V fresh battery reads 9.30 V, and an ideal ammeter briefly connected across the same battery reads 3.70 A. We say the battery has an open-circuit voltage of 9.30 V and a short-circuit current of 3.70 A. Model the battery as a source of emf ε in series with an internal resistance r. Determine both (a) ε and (b) r. An experimenter connects two of these identical batteries together as shown in the figure below. Find (c) the open-circuit voltage and (d) the short-circuit current of the pair of connected batteries. (e) The experimenter connects a 12.0-Ω resistor between the exposed terminals of the connected batteries Find the current in the resistor. (f) Find the power delivered to the resistor. (g) The experimenter connects a second identical resistor in parallel with the first. Find the power delivered to each resistor. (h) Because the same pair of batteries is connected across both resistors as was connected across the single resistor, why is the power in part (g) not the same as that in part (f)?
