Q7.31Multiple choice
In the LCR circuit shown in Fig 7.7, the ac driving voltage is v = vm sin ωt.
This question refers to a figure in the original PDF.
- (i)Write down the equation of motion for q (t ).
- (ii)At t = t 0, the voltage source stops and R is short circuited. Now write down how much energy is stored in each of L and C.
- (iii)Describe subsequent motion of charges. R L Fig. 7.7
