Answer / michael

R = V/i = 10/2 = 5 ohms

Inew = 1volts/5ohms
Inew = .2A

note: if the polarity is reversed I = Inew X 2
so I = .4A
thats is the correct answer..
if there is a word "polarity is reversed
multiply the current by 2

Answer / iamdon

From the first statement of line..
Resistance of branch=10/2=5 ohm

Current flowing through the branch=1/5=0.2A

can you use 400 volt 3 phase and neutral and earth equipment on 440 3 phase and earth supply safely and if so how?
