# Superposition with dependent sources

If the value of a dependent source (say CCCC) depend on the value of an independent source (say a current source). When setting the current source to 0, would that make the CCCC an open circuit (i.e. set to zero) as well?

The answer is to treat the CCCS as you would any other source acting alone, i.e. generating it's specified current, say $$\kI_x\$$, which is dependent on the current in the nominated path, $$\I_x\$$. You must not use the trivial solution, $$\I_x =0\$$ at this stage; doing so is a common error.
