An L-C-R series circuit , connected to a source E, is at resonance. Then,A. the voltage across R is zeroB. the voltage across R equals applied voltageC. the volatage across C is zeroD. the voltage across C equals applied voltage

Answer» Correct Answer - B
Equation of voltage , E = `sqrt `
At resonance (series circuit)
`underset(L)(V)` = `underset(C )(V)` `implies` E = `underset(R )(V)`
i.e., whole applied voltage appeared across
