Can I Use my Multimeter to Test How Much Power my Appliance (TV) is Using?

I wanted to know if my TV actually uses only 50W of power.

If it’s possible to use a multimeter to check, how do I do it and what should I avoid?

Another free way of doing this is to use the power meter outside your home.

turn everything using power off

verify by ensuring the power meter is no longer moving; no electricity consumed

record current reading

turn on tv for some period of time

record new reading

Calculate usage as difference of the readings divided by how long you ran the tv for.

Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.

Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.
