How to calculate the energy consumption per day and month if the ticks show 12A?
Hello. Please tell me how to calculate the consumption of electricity using current clamps? The ticks I measure show 12 amperes. How to calculate how many kilowatts are deducted per day and per month. What is the formula?

In this case, it all depends on what kind of load it is. If this is a purely active load (heater, electric furnace, heating elements, etc., incandescent lamps), then in this case, in order to determine the electricity consumption in a single-phase network, the current must be multiplied by the voltage in the network. If the voltage is 220 V, then the power consumption will be 12 * 220 = 2640 watts. If the load is not purely active, then you need to multiply by cosφ, which is different for each electrical appliance.
The resulting power value is the amount of electricity consumed per hour. Multiply by the number of hours during which the load flows, and get the energy consumption. But you keep in mind that the current can vary depending on what kind of consumers you have and, accordingly, your calculation will be incorrect.
You can accurately determine the amount of electricity consumed by the meter, recording the initial and final readings for the period of operation of this load. There are also portable meters in the socket, which allow you to find out the amount of electricity consumed by the included appliance.
