In a parallel circuit, ET = 240 V, R = 27 kΩ, and XL = 47 kΩ. What is IT?

Step-by-step explanation:

To find

total current = IT = ?

in parallel resistor inductor circuit = ET = EL = ER = 240V

IT = Square root [ (IR) ² + (IL) ²]

IR = ER/R

= 240V / 27kΩ

= 240V / 27000Ω (IKΩ = 1000Ω)

= 0.008 ampere.

IL = EL / XL

= 240V / 47 KΩ

=240 V / 47000Ω (IKΩ = 1000Ω)

= 0.005 amperes

IT = Square root [ (0.008) ² + (0.005) ²]

= Square root [ 8.9 * 10^-5]

= 9.4*10^-3 ampere
