Answer in Brief
The potential difference across the resistor is 160 V and that across the inductor is 120 V. Find the effective value of the applied voltage. If the effective current in the circuit is 1⋅0 A, calculate the total impedance of the circuit.

Solution
We have,
VR = 160 V
VL = 120 V
`"V"_"net" = sqrt((160)^2 + (120)^2)`
` = 10 sqrt(256 + 144)`
` = 10 sqrt400`
` = 10 xx 20 "V"`
Vnet = 200 V
Inet = 1 A
`"Z" = "V"/"I" = 200 Ω`
