Any two sources of electric current

Complete question is;

Name any two sources of electric current

Generators

Electrolytic cells

Explanation:

There are two main sources of electric current namely using generators and also by use of Electrolytic cells.

Generators make use of mechanical energy like water flowing through a dam or even the motion of a steam driven turbine to supply adequate voltage that's necessary to generate an electric current while Electrolytic cells make use of chemical energy to supply adequate voltage that's necessary produce electricity.

divide the right side by the left side

0.024÷1.2=0.02 for example

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
