BOSER Quiz 2 EECS 42/100 Thursday, 2/7/2008 SPRING 2008 Name: _____________________________ Section: ___________________ SID: _____________________________ 1. One 2V battery supplies 10mA to a circuit. How much energy does the battery supplies in 10 second? E = P * t = (I * V) * t = (2 * 10m) * 10 = 200mJ 2. In the circuit below, which element is dissipating power? (V 1 =5V, I 1 =-1A) 3. If V x =3V and I x =-2A, determine whether the element is dissipating or delivering power. 1 2 + V 1 - I 1 - V x + I x dissipating delivering
