I'm here again. Thanks for sharing it with us

I made a request the other time to make a video on how to wire a cold room..

[@danielteyehuago1633]

I think i need to guy this IR tester

Fantastic!

Please i wanna ask a question outside of this video. According to the "On site guide" under cables ans their resistance. It states that 2.5mm² cable has a resistance of 7.41mOhms per metre. So i cut exactly 1m cable and use digital multimeter to measure the resistance and i had 0.00 ohm, but i had 0.50ohms when i used the clamp meter...
Please why didn't i get the 7.41mOhms as stated... Or what's the right instrument to use.
Thanks

Hi Dan, please check the title of the particular table you are referring to very well. That table is not related directly to the experiment you did.
For your experiment, you have to use the formula below:
Resistance formula: The resistance (R) of a conductor can be calculated using the formula: R = ρ * L / A, where:
o ρ is the resistivity of the material (ohm-meters)
o L is the length of the conductor (meters)
o A is the cross-sectional area of the conductor (square meters)
Resistivity of copper at 20 degrees celcius is 1.77 × 10⁻⁸ ohm-meter (Ωm)
In your experiment, your cable length is 1m
And the area of cable is 2.5mm2
Plugging in the values, you should get:
R = 1.72 x 10^-8 ohm-meters * 1 meter / 2.5 x 10^-6 square meters = 0.0074 ohms
Therefore, the resistance of 1 meter of a 2.5 mm squared copper cable should be approximately 0.0074 ohms.
Now, this may be why your first meter did not read: most meters are designed to read resistance above 200Ω some are also designed to read resistance above 1Ω
That means, if the resistance being measured is far below the minimum value of the meter, it may either not show anything at all, or it will show a wrong value. So check the range of resistance your meter can read. thanks
