Question
Given following setup of three wires in the plane of the page with I1 = 3 A, I2 = 6 A, I3 = 9 A (directions shown by the arrows) and each wire is separated by 4cm.
23) What is the direction of the magnetic field at wire 3 due to wires 1 and 2?
a) up
b) down
c) into the page
d) out of the page
e) zero
24) What is the direction of the force on wire 3 due to wires 1 and 2?
a) up
b) down
c) into the page
d) out of the page
e) zero
Shown below is an LRC circuit connected to an AC generator with R = 8?, XL = 48 ?, and XC = 37 ?. The generator voltage oscillates at a frequency of 60 Hz. The maximum current in the circuit is measured to be 0.5 A
30) What is the maximum voltage across the inductor?
31) The frequency is changed to now be at the resonant frequency of the circuit (but the voltage of the generator stays the same). What is the impedance of the circuit?
