In an
L C R
circuit, if '
V
' is the effective value of the applied voltage,
V_R
is the voltage across '
R
', '
\mathrm{V}_{\mathrm{L}}
' and '
\mathrm{V}_{\mathrm{C}}
' is the effective voltage across ' L ' and '
C
' respectively then
Choose the correct answer:
A
\mathrm{V}=\mathrm{V}_{\mathrm{R}}+\mathrm{V}_{\mathrm{L}}+\mathrm{V}_{\mathrm{C}}
B
\mathrm{V}^2=\mathrm{V}_{\mathrm{R}}^2+\mathrm{V}_{\mathrm{L}}^2+\mathrm{V}_{\mathrm{C}}^2
C
\mathrm{V}^2=\mathrm{V}_{\mathrm{R}}^2+\left(\mathrm{V}_{\mathrm{L}}-\mathrm{V}_{\mathrm{c}}\right)^2
D
\mathrm{V}^2=\mathrm{V}_{\mathrm{L}}^2+\left(\mathrm{V}_{\mathrm{R}}-\mathrm{V}_{\mathrm{C}}\right)^2
