During electrolysis, positive ions migrate towards the cathode (negative electrode) and get reduced. In the case of CuSO4, Cu ions get reduced and deposited onto the cathode.Incorrect options: (a) The anode is where oxidation occurs, not deposition of copper. (c) Copper is specifically deposited at the cathode during the electrolysis of CuSO4. (d) Copper is indeed deposited during the electrolysis process.

Correct answer: B. deflecting plates

  • A. ink pump
  • B. deflecting plates
  • C. charging electrodes
  • D. gutter

Explanation

In inkjet printers, the computer sends instructions to the deflecting plates, which precisely control the direction of the ink droplets as they are ejected onto the paper to create the desired image or text.Incorrect options: (a), (c), (d) These components may be present in inkjet printers, but they do not directly receive instructions from the computer regarding the printing process.

About Current Electricity

Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
