4 loads are connected in series across 120volts and 3 ampere current exists.one load fail to perate.the voltage across each divece is 40 volts.what circuit fault is indicated?

 

Is there 40V across the load which fails to operate? Or only the other three loads?

Have you taken a look at the material in the AAC ebook at www.allaboutcircuits.com ? I think it would supplement the material in your textbook nicely.

Koky, the problem description you have provided is incomplete.

 

Hello,

If the voltage accross each remaining element is 40 Volts.
How many volts are there accross the "defective" element?
What is wrong with the "defective" element?

It sounds like the answer must be "short circuit". An open circuit would result in 0V across each device.
