A fluid composed of a solution of charged ions flows through a pipe. At a junction with another pipe, more of the charged solution is added. The combined stream continues onward in the main pipe which maintains the same dimensions it had before the junction.

Required:
What best describes the current and current density of the solution in the main pipe both before and after the junction?

At a constant area of the pipe, when more charge is added, the current flowing in the main pipe after the junction will increase and the current density will increase as well since it is directly proportional to the amount of charge flowing in the pipe.

Current is defined as the quantity of charge flowing in a circuit at a given time.

Current density is defined as the quantity of charge of flowing per unit area of the pipe.

[tex]J = \frac{I}{A}[/tex]

where;

  • J is the current density
  • I is the current flowing in the circuit
  • A is the area of the pipe

After more charge is added into the pipe, the quantity of charge flowing in the main pipe will increase and the current density will increase as well since it is directly proportional to the amount of charge flowing in the pipe.

Thus, at constant area of the pipe, when more charge is added, the current flowing in the main pipe after the junction will increase and the current density will increase as well since it is directly proportional to the amount of charge flowing in the pipe.
