- What is the VCC1's power source. Is it a battery? By the way, 220 Ohm is pretty low value. That will result in 22mA of current (at 5v) going into the base. With a gain of 270 that would result in a collector current of around 6A. I'd try using increasing the resistors to 1 kOhm to 5 kOhm.Gerben– Gerben2014-12-28 18:53:10 +00:00Commented Dec 28, 2014 at 18:53
- @Gerben: Ahh .. I see I may have messed up. I reduced the resistance. I'll try increasing it before I switch to a different circuit per Mark Williams belowRickMeasham– RickMeasham2014-12-29 01:39:34 +00:00Commented Dec 29, 2014 at 1:39

How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. arduino-uno), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
