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 / iamdon
From the first statement of line..
Resistance of branch=10/2=5 ohm
Current flowing through the branch=1/5=0.2A
