1.) Two inductors each have an inductance of 2H, the mutual inductance between them is M=0. Calculate the inductance if a) they are connected together correctly in parallel b) they are connected together correctly in series 2.) Two inductors who share a coil each have an inductance of 2H=L1-L2, M=0.6H. Find the resultant inductance if they are connected together a) correctly in parallel b) incorrectly in parallel c) correctly in series d) incorrectly in series 3) A square magnetic core has a mean path 1-55cm, a cross sectional area A=150cm², N=200 turns, flux p=0.012 Wb, H=115 ampere-turns /meter a) find the current in the wire b) find the relative permeability c) find the reluctance. 4) We have a 1:1 transformer that we are looking at rated at 120V. The right side of the transformer has 2 coils rated at 120 v each C2 and C3. The left side is C1. They are all identical. |:|| Find the max voltage on the right side if a. output voltage of C2 if 120v applied to Cl b. output voltage of C3 if 120v applied to C1 c. output voltage of right side if 120v applied to C1, C2 and C3 are in series d. output voltage of right side if 120v applied to C1, C2 and C3 are in parallel 5) A designer has to keep the current density at or below 1200 A/sq in. What gauge wire would the designer use for a load using 25 amps? 12.5 amps? Hint: Look up AWG The LabVolt equipment has inductors, resistors, and capacitors which have values of 300ohms, 600 ohms and 1200 ohms (based on 60Hz). It also has voltages available of DC, 60Hz and 50Hz. Voltage meters, current meters and power meters are available. 6) The values of resistance vary depending if the current is AC or DC with the 60 Hz AC values being about 5% higher. Design an experiment to test the value of the resistor and determine if the above statement is true. 7) The reactance value of capacitors and inductors change with frequency. Design an experiment to determine if the above statement is true. Pick either inductors or a capacitors to test. (Do not use DC in this experiment.) Remember to connect a resistor load in this experiment. 1.) Two inductors each have an inductance of 2H, the mutual inductance between them is M=0.
