A resistor `R` an inductance `L` and a capacitor `C` are all connected in series with an ac supply The resistance of `R` is `16ohm` and for the given frequency the inductive reactance of `L` is `24` ohm and the capacitive reactance of `C` is `12ohm` If the current in the circuit is `5A` find
(a) the potential difference across `R,L` and `C`
(b) the impedance of the circuit
(c) the voltage of the ac supply and
(d) the phase angle .

Explanation

Phase angle
`phi=tan^(-1)[(omegaL-(1//omegaC))/R]`
`=tan^(-1)[(24-12)/16]`
`=tan^(-1)(0.75)=36^(@)87^(')`
