Given : Voltage across an inductor `V_(L)=10V`
Voltage across an capacitor `V_(c)=10V`
Voltage across resistance `V_(e)=30`
Phase difference between applied voltage and
Solution :
current in the circuit `tanphi=(V_(L)-V_(C))/(V_(R))`
`tanphi=(10-10)/(30)`
`tanphi=0`
`therefore"phase difference"tanphi=0.`
