Question

In the given circuit, assuming point $A$ to be at zero potential, Use Kirchoff's Rule to determine the potential at point $B$.

Answer 1

In $1^{st}100p$

$-R+1+2=0$

$\Rightarrow R=3\Omega$

In $2^{nd}100p$

$-2R_1+2-2=0\Rightarrow R_1=0$

Now going from point A to B viac .

$V_A+1-0=V_B\Rightarrow V_B=1V$
