A gauge 14 extension cord can safely carry 15 A What will happen if several appliances drawing a total current of 18 A will be connected to it?

A 14 gauge extension cord can safely carry 15 amps, but not very far. Number 14 gauge extension cords are only rated for about 13 amps according to the labels on the cord. This is because the insulation is not intended to withstand the heat of currents above this level. Running this cord over 50 feet or loading it to 18 amps would be unacceptable.The likelihood of the cord maintaining the 18 amps for any amount of time for the high current to do any damage to the insulation of the cord is not very great. Extension cords are only an extension of the 15 amp wall circuit that they are plugged into. On overloading the extension cord by that amount the overload will trip the 15 amp supply breaker. An example of this is jamming a circular handsaw when it is plugged into the end of a 50 foot extension cord. The next action that is taken is to reset the tripped breaker.

Why one phase is hotter in commercial buildings?
The service is not balanced, one leg is drawing more current that the others.
What is a stand by current?
Standby current is the current that a device draws when it is not actively performing its function. This current would be measured in amperage, and commonly amperes, milliamperes or microamperes would be the units of measurement. As an example of a device drawing standby current; a radio transmitter may not be actively transmitting, but the power supply is turned on, and the transmitter is ready to operate. In this case, the transmitter is drawing very little power. A computer can be in standby mode and drawing "standby current" , examples of which are also "hibernation" and "sleep" modes. The computer display and hard disk drives are turned off, and the CPU is throttled down to low power state. However, memory is kept active, which requires just a small amount of battery power.
Does a 900 to 950 watt require a separate electrical circuit?
Depends more on the application and what else you might have on a current circuit you would use if you didn't install a separate circuit. At 120 volts you are only talking about drawing 8 amps. On a 15 Amp circuit this is fine. However, if there is a motor involved there may be excess start-up currents. There are certain appliances like stoves, refrigerators, dryers, dishwashers and so forth that require separate circuits. If you have a small heater you move from room to room then you can use an existing circuit that would not trip when you added the appliance. Use the cord that comes with the device directly into an outlet rather than using an extension cord. If the appliance needs to be hardwired into a box then use a dedicated circuit.
The drawing of an electrical circuit is called a?
schematic drawing
If a 325 watt heater has a current of 6.0A what is the resistance?
Watts = Current x Volts with your resistive heat application. To figure out resistance you need to know voltage and current. Since you are drawing 6 amps then Volts = 325/6. This means that there is about 54 volts supplying the heater which seems like a very strange supply voltage. Since Volts = Current x Resistance the resistance = 325/36.
Why is ammeter connected in series with the load?
A ammeter will tell you how much current draw the load is drawing
What is the voltage of common electrical appliances?
115 volts <<>> In North America because of using a split secondary both 120/240 voltages are common. 120 volts used for smaller appliances and lighting systems. 240 volts used for larger appliances. Keeping in mind that the higher the voltage the lower the current, using higher voltage on larger current drawing appliances keeps the wire to a workable size.
Three identical bulbs are connected in parallel with a battery of 6A If one of the bulb gets fused what will be the total current drawn from the battery?
As the lamps are identical, and all three draw a current of 6 A, then each lamp must be drawing 2 A. So, with one of the lamps disconnected, the current drawn from the supply will reduce to 4 A.
What is a coherent drawing?
you can draw some think like two brains connected by waves, hence logically connected, i have done this personally for a Jr.high assignment.
What must you consider before using a long extension cord wound on a reel?
Many things. What current you will be drawing, will the cord have to be fully extended, will the voltage drop affect the tool you are using, is the cable going to be a trip hazard. Depending on the circumstances and situation there are others too.
After connecting positive the negative sparks?
Then something is turned on and drawing current.
Is a circuit breaker a protective device?
yes when combined with a suitable protective relay
Why would wire harness to blower motor resistor melt down?

Why is it not a good idea to use a penny instead of a fuse?
Fuses are made for a reason, they burn before your wires/ appliances, by using a penny, if you are drawing too much current, and run the risk of burning down your house, your penny wont burn, in turn burning your house down. Hope I helped
Why isn't your circuit breaker staying on?
Assuming the circuti-breaker itself is working correctly, it's telling you there is a fault somewhere - either an actual short-circuit or your appliances etc combined are drawing more current than the circuit's rating. Do not ignore it, otherwise you run the serious risk of fire.
Why is the earthing system drawing current?
There is a short circuit somewhere in the electrical system.
