Question

Formulate a hypothesis about the equivalent inductance?

In class we have studied the effect of connecting resistors in series and parallel and have computed formulas which describe the equivalent resistance for these cases We have also done the same for capacitors which are connected in series and parallel However, we have not done the for inductors. formulate a hypothesis about the equivalent Inductance. L , of two inductors. L1 and L2 connected in series Write your proposed formula on the line below. Formulate a hypothesis about the equivalent inductance, L . of two inductors, L1 and L2 connected in parallel Write your proposed formula on the line below. Explain any reasoning you used to help arrive at your hypotheses. Design an RL circuit involving the two inductors which would allow you to test your hypothesis by measuring the equivalent inductance of two inductors in series. Do the same for the two inductors in parallel. Draw circuit diagrams (neatly, please) for each case. Make sure you also show how any meters or measuring devices would have to be hooked up to your circuit. Explain how determining the time behavior of these circuits allows you to measure the equivalent inductance.

Explanation / Answer

emf=ldi/dt
connect parallel
inductance Net value(Vnet)=l(di1+di2+di3)/dt
vnet=l(v/l1+v/l2+v/l3)
when 2 parll point value
lnet=l1*l2/l1+l2
A)=series add value
v1+v2+v3
emf=l1+l2+l3+l4...........
