Workshop Problem Week 11Due Friday, April 16, 2010 along with your problemassignment.1. Find the currents I1 and I2 and theunknownbattery potential difference V.2. Consider the following circuit consistingofone battery and three identical resistors. Explain yourreasoningor show your work for each answer.A. If the circuit contains a 13.0 V battery,howmuch charge must pass through the battery to deliver 72 J ofenergyto the circuit? (Hint: define power generallyandelectrically.)AB. Suppose, instead, the circuit contains a 1.5 V battery. Howmuchenergy is delivered to resistor 1 when 12.5 C of chargepassthrough the battery?C. Suppose we want to deliver 8.5 J of energy to resistor 3. Whatisthe required battery voltage if this is to be accomplishedbypassing 4 C of charge through the battery?
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)?
The capacitors in each circuit (a) through (d) pictured to the right, discharge when the switch closes at t=0 seconds. Rank in order from largest to smallest, the length of time it takes for the circuit to discharge i.e the time constant for each circuit. The individual capacitors all have the same capacitance and the light bulbs are identical in all circuits.
