A current of 5.0 A flows through a 0.50 m length of wire connected to a 4.5 V battery. a What is the resistance of the wire? b What is the electric field in the wire? c A 1.0 m length of the same wire is connected to the battery. What current will flow through the wire?

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.

i think the answer is a, hope this : )

god i hope this !
