Answer to Question #83304 in Electric Circuits for Gwen

Question #83304

How much current passes through the 20-kΩ resistor when the resistors ( 20 kΩ, 30 kΩ, 60 kΩ) are connected in series with a 220 V source?
a. 2 mA
b. 11 mA
c. 20 mA
d. 110 mA

Expert's answer

Correct answer: a.2mA

R_Total=20+30+60=110 kΩ

I=U/R_Total =220/110000=2 mA
