Problem

Four conductors meet at a single point. Currents of

1.2\,\text{A}

and

0.7\,\text{A}

flow toward the junction along conductors A and B, respectively. Along conductors C and D, currents of

0.4\,\text{A}

and

I_D

flow away from the junction. Verify whether the current assignment satisfies conservation of charge. If it does not, determine the correct value of

I_D

that restores consistency.
