How many volts in 1200 watts?
Wattage is unit of power which is the product of Voltage in V and Current in Amps. If you know the current drawn by the appliance with 1200 Watts then you can calculate the Voltage = Power/ Current. For eg. if the current drawn by the appliance is 100A then the voltage is 1200/100 i.e. 12 Volts.
What is rated normal current?
The rated current is the maximum current that can be drawn in normal continuous use, without any reduction in the lifetime of the device.
Why terminal potential difference is decrease when current in the circuit is increased?
If the terminal voltage decreases when more current is drawn, that is due to the internal resistance of the power supply. Every power supply has a limit to how much current can be drawn. It is limited by the internal resistance and due to ohms law the more current drawn through a resistor, then the more voltage is produced across it. This is in opposition to the terminal voltage and is subtracted from it.
What does the slope of voltage-current curve represent?
It depends. If voltage is drawn along the horizontal axis, then the slope at any point on the graph represents the reciprocal of resistance at that point. If current is drawn along the horizontal axis, then the slope at any point on the graph represents the resistance at that point.
What size resistor is needed to drop 14 volts dc to 12 volts dc?
This question cannot be answered because you did not specify the current.
How much current is drawn when an appliance rated at 795 W is plugged into a 120 V wall outlet?
it is 795 divided by 120. <<>> The formula you are looking for is I = W/E, Amps = Watts/Volts.
What amp circuit breaker should be used for a 120v 2.5 amp appliance?
If the appliance is just to be plugged into a circuit with multiple outlets then you just need to make sure that the sum of currents for all devices on the circuit are less than the rated current. A rule of thumb is total current should be no greater than 80% of the rated current. So you might have a 20 A breaker and several 2.5 A appliances on this circuit. If you have a dedicated circuit for the appliance you would only need to size the breaker for the maximum current being drawn by the appliance. If the appliance contained a motor then there might be a start-up current that might be as high as 15 amps so you would likely go to a 20 amp breaker for a safety margin. As a practical matter a dedicated circuit for an appliance in the 2.5 amp range should have a 15 amp breaker. I always install a 20 amp breaker just for added margin and possible future applications.

Can you use transformer with your 110 aircon?
A transformer can be used to change the voltage to an appliance. The voltage rating of the transformer should be right for the voltages used, and the current rating of the transformer should not be less than the current drawn by the equipment.
Can an extension cord plugged on a 230V socket outlet be used to connect a fully wired container with a distribution box?
You should know the maximum current drawn from the distribution box (in amps) and that must be less than the current that the extension cord is able to supply.
Does a toaster use electric if plugged in?
Toasters and similar appliances use no power unless they are operating. Even if they are plugged into a mains supply, no current will be drawn unless the bread carrier is lowered to its operating position. However, it is good practice to disconnect appliances if they are not going to be used for long periods of time.

Is there a device that can be plugged into a vehicles cigarette lighter that you can plug an electrical chord into?
Yes there is. They are not commonly available. The device is called an "inverter". In a solar cell installation on a house, the solar cells produce direct current (DC) and charge batteries, such as 12 volt batteries. The inverter then converts the 12 volt DC power to 110 volts AC, or house current. In a car, you need to take 12 volts DC from the battery and convert it into 110 volt AC power, to plug in say a household apppliance. You would need to go to a car accessories company (look for one on the web). A caution: since you are converting 12 volts to110 volts, the current drawn from the car will be about 9 times as many amperes as the AC current rating on the 110 volt household appliance. For any sizeable appliance, this will over-tax the current capacity of the cigarette lighter. First, the fuse in the car will blow. If you intend to use a 110 volt appliance regularly from a car, then you can buy a large inverter that can be mounted in the car and wired to the battery. Depends on what kind of appliance you are trying to run.
What is load current?
It is a the current drawn by the application that is connected to the power source
Why are fuses in plugs?
to provide 'over current' protection due to overload or failure of the appliance, device and also the associated wiring. If the appliance or device draws more current than allowed, the fuse will melt first and open the circuit thus stopping the flow of current. Without a fuse there would be no limit to the current being drawn, the device and also the wires feeding it could overheat or even catch fire. The plug provides a convenient location for the fuse and also allows the fuse to be appropriately sized for the particular device being used.
What is the maximum current that can be drawn from a voltage source?
The maximum current that can be drawn from a voltage source is dependent on the impedance of that source, the impedance of the connections to the source, and the energy available from that source.
