An ac source of rms voltage V is put across a series combination of an inductor L, capacitor C and a resistor R. If V_(L), V_(C ) and V_(R) are the rms voltage across L, C and R respectively then why is V ne V_(L) + V_(C ) + V_(R) ? Write correct relation among V_(L), V_( C) and V_(R).

Answer»

Solution :`V_(L), V_( C) and V_(R )` are not in the same phase
`V_( L) + V_(C ) + V_(R ) GT V`
