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