Question 94Electricity & Electronics - QMED

A) electromotive force is the correct answer. The electromotive force (EMF) is the force that causes free electrons to flow in a conductor, producing an electric current. This force is generated by a voltage source, such as a battery or generator, and drives the electrons through the conductor. The other options are incorrect because: B) Dielectric force refers to the attractive force between opposite charges in an insulating material, not the force driving current flow. C) Inductive force is the force that induces a current in a conductor due to a changing magnetic field, not the primary force causing current flow. D) Resistant force is not a recognized term in this context; it likely refers to electrical resistance, which opposes current flow, not drives it.
