Question

An inductor is perhaps the simplest electrical component we have observed: a simple coil of wire. Suppose you make an inductor by coiling some wire, but it doesn't have enough inductance for your circuit. How can you increase your inductance?

	a.	Add additional turns of wire, or insert a ferromagnetic core.
	b.	Remove several turns of wire, or insert a ferromagnetic core.
	c.	Use thicker wire, or insert a ferromagnetic core.
	d.	Remove several turns of wire, or insert a plastic core.
	e.	Add additional turns of wire, or insert a plastic core.
