(LIFE SAFETY WARNING! [disclaimer]
Electricity is dangerous!
You can be injured or killed!
Improper installations can cause fire, injury and death!
Should you be doing this yourself?)
How do you calculate the load? Every situation is unique. How do you cook dinner? Do you have pork or tofu? Get a cookbook.
The basic information is in the National Electrical Code:
Article 210.18, 220.25
Article 220
Article 430
Article 520
Article 550
p.s. - [hint] Electrical equipment is allowed to be operated continually [over 4 hours] at 80% of nameplate [nominal] rating, unless rated for other loads. This would suggest you can load your panel at 160 amps at 240 volts forever.

I think the answer above is a very good one but may be more academic than you are looking for. You are probably thinking of adding something on and took a look at your service panel. If you start adding up the individual breaker amp ratings you will come up with a number that far exceeds the 200 amp main rating, that is not the way loads are calculated on services, if you have breaker space and unless you double the floor space of your home you should be able to safely add load to your 200 amp service.
<><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

∙ 13y agoTo calculate the load on an electrical panel, you add up the amperage ratings of all the devices connected to it. For a 200A service panel, you should not exceed 200A total load to avoid overloading the panel. Make sure to consider that some devices may draw more power when starting up (such as motors or HVAC equipment). It is advisable to consult with a qualified electrician to ensure the panel's load does not exceed its capacity.

∙ 10y agoThe maximum load of a 200 amp panel is 200 amps. To find out what is being pulled through the panel you would have to add up every single electrical powered device in your home. As all of those devices are not all on at the same time that is really meaningless. Adding up all the breakers is also meaningless. Your electric company can tell you the average load your home is pulling.
Electrical current is the measure of the flow of electrons, measured in Amperes (Amps). An example would be to compare it with a fluid flow meter. As opposed to pressure, which is analogous to Voltage.
Something that when touched cannot allow an electrical current to pass through it, an example of a non-conductor would be wood.
An electric current primarily consists of the flow of electrons through a conductor, typically in a closed loop circuit. This movement of electrons generates a flow of charge that can be harnessed for various applications, such as powering electrical devices.
An example of converting electrical energy into magnetic energy is when current flows through a coil of wire, creating a magnetic field around the coil. This is the principle behind electromagnets where the coil becomes magnetized when current passes through it.
Electrical appliances use inductors to store and release energy in the form of a magnetic field. They are used to smooth out variations in current and voltage, filter out noise, and regulate the flow of electricity in devices like transformers, motors, and power supplies.
An electrical circuit is an example of an electrical pressure to electrical current convertor.
example of devides that can convert to elecrical energy
Voltage x current. In a resistor for example it is the voltage drop across it that is relevant, it may be part of a circuit.
One example is a battery, which converts chemical energy into electrical energy through a chemical reaction that causes the flow of electrons. This flow of electrons generates an electric current that can be used to power electronic devices.

please answer me with some example
For example the electrical current.
BJT is a example for current controll device. And JFET is a voltage controlled device.
Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.
Anything that uses electricity. For example, a light-bulb.
Electrical current is the measure of the flow of electrons, measured in Amperes (Amps). An example would be to compare it with a fluid flow meter. As opposed to pressure, which is analogous to Voltage.
Lightning is an example of electrical energy found in nature. Lightning is a natural discharge of static electricity that occurs during thunderstorms, creating a powerful electrical current.
