4. Three inductors with inductances, L1 = 1 H, L2 = 2 H, and L3 = 3 H, are connected to a 5-V power source. What is the effective inductance when the inductors are connected in (a) series (b) parallel.
I am really need these solutions. Can your help me please?
this is a last part for my class final. I am really stuck at
it

need help with the FBD, the unknowns, and L1 and L2
thank you
In this case both top and bottom supports of the PVC pipe are fixed. There is only one lever arm at the center of the pipe where torque is caused by applying weights of 5 N on each side of the hanger. Place dial gage at the point where load is applied to measure the deflection caused by it. After making the initial reading zero on the...
