Steady current does not change with respect to _.

Explanation

Option A) Conductor, is not the correct answer because the amount of current flowing through a conductor can vary depending on its resistance, length, cross-sectional area, and other physical properties. Option B) Source is also not the correct answer because the amount of current supplied by a source can vary depending on its voltage, internal resistance, and other factors. Option C) A constant current (steady current, time-independent current, stationary current) is a type of direct current (DC) that does not change its intensity with time. Option D) Potential difference, is also not the correct answer because the amount of current flowing through a circuit is directly proportional to the potential difference applied across it, according to Ohm's law. Therefore, if the potential difference changes, the current will also change proportionally.
