&lt;p&gt;&lt;b&gt;새 문서&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== 개요 ==&lt;br /&gt;
다리가 세개있는 BJT 트랜지스터는 교류전류에 쓰이면 증폭기, 직류전류에 쓰이면 스위치가 된다.&lt;br /&gt;
관련된 많은 내용은 일단 덮어두고, 일단 일반적으로 쓰일 수 있는 트랜지스터 스위치를 만든다. &lt;br /&gt;
여기에서는 2n2222a npn 트랜지스터를 사용해 직류보터를 돌려본다. pnp보다는 npn을 사용한 회로가 더 직관적으로 이해가 쉽고, 그중에서도 2n2222a 가 허용전류등의 면에서 범용적으로 쓰이기 알맞기 때문이다.&lt;br /&gt;
