The current though a branch in a linear network is 2A when
the input voltage is 10 volts. If the voltage is reduced to
1 volt, and the polarity is reversed, what is the current
flowing through the branch ?

Answer Posted / 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
