In an L-C-R circuit, if V is the effective value of the applied voltage `V_(R)` is the voltage across R, `V_(L)` is the effective voltage across L, `V_(C)` is the effective voltage across C, then

Options

A. `V=V_(R)+V_(L)+V_(C)`
B. `V^(2)=V_(R)^(2)+V_(L)^(2)+V_(C)^(2)`
C. `V^(2)=V_(R)^(2)+(V_(L)-V_(C))^(2)`
D. `V^(2)=V_(L)^(2)+(V_(R)-V_(C))^(2)`
