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, - Physics

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`
