Keisha analyzes this circuit diagram. which circuit component should keisha use to start or stop the current in the circuit? w x y zanswer a

1/0.14nm = 10^10/1.4 a lot

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.
