Workshop Problem Week 11
Due 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.)
A
B. 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?
