The current in the iron can be calculated using the formula P = V * I, where P is power (2 kW = 2000 W), V is voltage (100 V), and I is the current. Rearranging the formula to solve for I, we get I = P / V. Substituting the values, the current in the iron is 20 A.

A current carrying wire wrapped around an iron core?
This setup creates an electromagnet where the iron core increases the magnetic field strength produced by the current flowing through the wire. The strength of the magnetic field can be further increased by increasing the number of turns of wire around the iron core or by increasing the current flowing through the wire. Electromagnets are used in various applications such as in electric motors, generators, and magnetic resonance imaging (MRI) machines.
What object weights 100 tons?
A large anchor used for ships can weigh around 100 tons. These anchors are made of heavy materials such as steel or iron to effectively hold a ship in place.
Suppose a wire whose resistance is 2.5and 1.0 Amp of current for 1 second raises its temperature by 100 C What is the amount of current required to raise the temperature 100 C in 0.5 seconds?
If the wire's resistance is 2.5Ω and 1.0A of current for 1 second raises its temperature by 100°C, then the power dissipated is 2.5W. To raise the temperature by 100°C in 0.5 seconds, you would need to double the power output, which means you would need 2.0A of current.
What is the current in a 100-ohm resistor connected to a 0.40-volt source of potential difference?
The current flowing through a 100-ohm resistor connected to a 0.40-volt source can be calculated using Ohm's Law, which states that current (I) = voltage (V) / resistance (R). In this case, I = 0.40V / 100Ω = 0.004 amperes, or 4 milliamperes of current.
What is a medium frequency current?
A medium frequency current refers to an alternating current with a frequency typically between 1 kHz and 100 kHz. It is used in various electrical applications including industrial processes, medical treatments, and welding. The medium frequency range offers a balance between the skin effect of high frequencies and the power transmission efficiency of low frequencies.
What is the device which works both as rectifier and inverter?
The only one I can think of is known as an "Uninterruptable Power Supply" or U.P.S. for short. Usually connected to computers or to other equipment where they provide D.C. or direct current output from A.C. ( alternating current ) mains. Inside there are one or more batteries that are charged when the mains are on. The rectifier side creates the direct current. When the mains fails the inverter side of things may take the power from the battery, creating an a.c. supply which could be used by the rectifier side for the output. Although I'm an electrician, I've never taken one apart to have a look or even seen the circuit diagram for one so I would not take this as a 100% accurate answer.
How do you increase current capacity of an ammeter?
In measuring high AC currents a current transformer with a suitable rating say 100/5 or 1000/5 are used. The secondary current is usually 5 amps when the fulload current of 100 or 1000 as the case may be is flowing in the mains. It is the univerasl practice to use CT's for measurement of AC currents. In DC circuits the transformer method will not work, so to increase the current that you can measure you can allow a known amount of current to bypass the ammeter and recalibrate the ammeter. In other words, put a shunt in parallel with the ammeter.
Is tube light need dc voltage?
If you mean a Fluorescent tube light then no, you don't need DC. Household Fluorescent light tubes use AC mains electricity. The mains AC is passed through a ballast coil which reduces the current. A ballast coil works best when the AC mains voltage is at least 2 times the Fluorescent tubes working voltage. So, a simple inductor ballast can be used in Europe, where the line voltage is typically 220 to 240 Volts AC, to operate a 4 foot long tube, which operates at 85 to 100 volts, depending upon design. In the US and other places that use 120 Volts AC mains, the ballast is a combination auto transformer (to raise the voltage) and an inductor (the current limiter).

What does a power cord do?
A power cord, line cord, or mains cable is a cable that temporarily connects an appliance to the mains electricity supply via a wall socket or extension cord. The terms are generally used for cables using a power plug to connect to a single-phase alternating current power source at the local line voltage"(generally 100 to 240 volts, depending on the location). The terms power cable, mains lead, flex or kettle lead are also used. A lamp cord is a light weight ungrounded two wire cord used for small loads such as a table or floor lamp. The term cord set is also used to distinguish those cords that include connectors molded to the cord at each end.
How many wheels on airbus A 318 100?
6. There are two mains, both with two wheels, and two on the nose gear.
How much is 100ah is equal to?
Commonly this figure is used for battery used for cars or UPS. 100Ah means, you can draw 100 Ampere current for one hour. Like a battery 0f 12Volt,7Ah can be used for a circuit which draw current of 1 Amp. can be used for approximately 7 hours.
Is current greater in electric iron or in bulb?
A running iron uses the same power as nine 100 watt bulbs.In the home, depending upon where you live, the service voltage is fixed at either 110 or 220 volts. Various appliances and devices require different amounts of energy, of course. Since the voltage (or pressure of delivery) is the same, the current (volume of delivery) is what changes.In round numbers, a clothes iron might draw 10 amperes of current at 110 volts, or 1100 watts of power. A light bulb might draw 1 ampere of current at the same voltage.It's easy to see that the iron will draw far more current than even an inefficient incandescent light bulb.
How do you calculate percentage in iron oxide?
The percentage of iron oxide in iron oxide is ... yep, you guessed ... 100%!
What is the first people to make extensive use of iron for tools?
I am not 100% sure if this is the correct answer since you used the word extensive... but the first people to use iron would be the Hittites.. While they created iron they could not create enough to be effective in the use of battle with the Egyptians... who used copper weapons.
