What else can I help you with?
Why are some appliances rated in watts and others amps?
Appliances are rated in watts to indicate the total power they consume, which is the product of the voltage and current they draw (P = V x I). Some appliances may also be rated in amps, which measures the current they require from the power source. Both ratings are important for determining electrical loads and ensuring safety.
Can you run 3 appliances 10-15 amps each through an extension cord with multiplug that is rated for 20 amps?
Not simultaneously because the total current must not exceed 20 amps.
How many amps per phase would a machine rated at 460 amps over three phases take?
It depends on the internal circuit of the machine. If it is star operated its full load current will be same as rated current. If it is Delta operated its full load per phase current will be as given below : Phase current = Line Current / 1.732
Can you use 240v appliances on 110v current?
No, the pin configuration of the 240 volt receptacle is different from a 120 volt pin configuration. This is a safety factor to prevent the wrong voltage being applied to the wrong device. If the appliance is an electrical heater, then operating a 240 volt unit on 120 volts would give you a reduced wattage factor. By halving the rated operating voltage you will only receive one quarter of the rated wattage from the unit. A 3000 watt heater at 240 volts will be reduced to 750 watts on 120 volts.
Which uses more electrical current a 13A kettle or a 13A iron?
An iron is going to use more electrical current than a kettle. The iron needs to be plugged in to stay hot. The kettle is usually unplugged after the contents reach the right temperature. <<>> The electric current drawn is the same for both appliances, 13 amps if they are both 13-amp devices. However an iron is usually a lower-power device of about 1 kW that would draw 4 amps on a 240 v supply, and its thermostat would operate to control the current so that it doesn't overheat. Some kettles have a 3-kW element which would draw 13 amps, but kettles are used only now and then. So both devices do not use a lot of energy.
Electrical appliances are rated in what electrical terminology?
Appliances are rated in UL (Underwriters Laboratory) listing, which is a safety testing laboratory, and are rated in watts.
Why are some appliances rated in watts and others amps?
Appliances are rated in watts to indicate the total power they consume, which is the product of the voltage and current they draw (P = V x I). Some appliances may also be rated in amps, which measures the current they require from the power source. Both ratings are important for determining electrical loads and ensuring safety.
What will happen if several appliances drawing a total current of 18A will be connected to it Explain?
If several appliances drawing a total current of 18A are connected to a circuit designed to handle that load, the appliances will operate normally without any issues, provided the circuit is rated for that current. However, if the circuit's capacity is lower than 18A, it could lead to overheating, tripped circuit breakers, or blown fuses, posing a fire hazard. It’s crucial to ensure that the wiring and circuit breakers are rated for the total current to prevent damage and ensure safety.
What kitchen appliances use least amount of energy?
I would suggest looking for EnergyStar rated appliances. These appliances can use up to 30% less energy than other appliances. Here's some info from Wikipedia: http://en.wikipedia.org/wiki/Energy_Star
A Type of power used by appliances in the homes is what?
home appliances are rated by watts or amps
How much electricity can bee rated appliances save?
40%
How does the fuse wire save your electrical appliances?
The fuse wire is rated for a specific amount of amperage. If the amperage exceeds that rating, the fuse wire will quickly melt. The current flow in the circuit is interrupted, thereby protecting the appliance from an overload condition.
What does the fuse protect in a plug?
The fuse in a plug protects the electrical circuit and connected appliances from excess current. If the current exceeds the fuse's rated limit, it melts and breaks the circuit, preventing overheating and potential fire hazards. This safety mechanism ensures that appliances are not damaged by electrical faults or surges. Overall, it plays a crucial role in maintaining safe electrical operation.
If a centre tap transformer rated as 12V-0-12V 1Athen what will be the secondary current of that perticular transformer?
The output voltage of a transformer is not connected to the maximum rated current. You state that the transformer is rated at 12-0-12 at a current of 1A, therefore the maximum (rated) current on the secondary would be 1A. Normally, transformers are rated in VA (volt amps) which is simply voltage x current, the voltage across the two 12v terminals would be 12+12 volts, making the rating of the transformer 24VA.
Can you run 3 appliances 10-15 amps each through an extension cord with multiplug that is rated for 20 amps?
Not simultaneously because the total current must not exceed 20 amps.
What is rated voltage and current in transformers and how to calculate them if given 50k VA?
Rated voltage is the voltage at primary side. Rated current can be found from the equation, Rated Current= Output KVA / Output rated voltage
What is the difference between nominal current and rated current of circit breaker?
They are the same.
