(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.

The 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.
electrical conductivity is a necessary property for wiring in our electrical world. xox
A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.
Divide its power rating by its voltage rating. These ratings are found on its nameplate. For example, a 3-kW kettle rated at 230 V will draw a current of approx. 13 A.
An electrical circuit is an example of an electrical pressure to electrical current convertor.

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.

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.
because it gives electrical thunderstroms
The rotational force of an electrical generator using magnetism to create an electrical current.
If you open part of the circuit (for example, with a switch), the current will stop flowing. Also, if there is no voltage driving the current (for example, if a battery runs empty), no current will flow.
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.
