Question

Consider the four circuits in the figure. They all have the same resonance frequency and are driven by the same emf. (Figure 1) ://session.masteringphysics.com/problemAsset/1167625/3/jfk.Figure.26.Q20.jpg Part A Rank in order, from largest to smallest, the maximum currents to. Rank currents from largest to smallest. To rank items as equivalent, overlap them.

Explanation / Answer

I4>I1=I2>I3....Proof: Since all the four circuits have same resonance frequency which is w=sqrt(LC) and in all the four circuits product of L and C is same==>circuits are in RESONANCE ;therefore current is proportional to 1/R...hence I4>I1=I2>I3.follows
