How to calculate the minimum load of a power supply?
If you are trying to calculate the minimum load and you happen to only know the power and voltage ratings of your power supply, you can use the formula P = V 2 /R,…
How to find out what your power requirements are?
There are many ways to find out what your power requirements are, but no matter what method you use, all computations involve three electrical concepts: 1 Current (amps) 2 Voltage (volts) 3 Electrical power (watts) More
How to calculate electrical circuit load capacity in your home?
Electrical circuit load capacity is the total amount of power that your home actually will use. In order to decide how big of an electrical service is needed in your home, one has to do a little math homework. Older homes often only had a 60-amp electrical service, connected to a fuse panel. Newer homes have 100- or 200-amp electrical services.
Why does my power supply run without a load?
Leaving an output without a load on it will cause this to happen. This is because for most switch mode and unregulated power supplies, the outputs need to be stabilized. Using Ohm’s Law: V = IR, you can calculate the minimum load if you know the voltage and minimum current ratings.

Hareendran – 07/13/21 This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T.
What’s the correct rating for a power supply?
If for any reason you only have the current and power ratings of your power supply, you can use P = I 2 R, which can be changed to R = P/I 2 .
