Question

Consider the two circuits shown in the figure. (Figure 1) The current in circuit 1, containing an inductor of self-inductance L, has an angular frequency ?1, while the current in circuit 2, containing a capacitor of capacitance C, has an angular frequency ?2. If we increase ?1 and decrease ?2, both bulbs grow dimmer.

If we keep w1 and w2 constant, we can achieve the exact same effect of decreasing the brightness of each bulb by performing which of the following sets of actions?

a) increasing C and decreasing L b) increasing both C and L c) decreasing C and increasing L d) decreasing both C and L

Explanation / Answer

c) decreasing C and increasing L
