Passing too much current through a mains cable can lead to overheating, which can result in the insulation melting and causing a short circuit. This can pose a fire hazard and increase the risk of electric shocks. Additionally, exceeding the current-carrying capacity of the cable can damage the electrical components connected to it.

What wave shape of the mains supply is know as?
The mains supply wave shape is known as a sine wave. It represents the alternating current that is provided by electrical utilities for powering our homes and businesses.
A 2 KW iron is used on a 100 V AC mains The current in the iron is?
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.
Properties of a resistors?
They are used in circuits and devices commonly (eg.the computer and TV) they slow the amount of electrons going through so that if you are plugged into the mains and have a light bulb that is small, the resistor would be put in place to the device eg.the light bulb doesnt burn out.
Which is more powerful a torch bulb or a mains filament bulb?
Mains filament
What is the function of bulb in frequency of ac mains by electrically vibrating rod?
The bulb in the frequency of AC mains by electrically vibrating rod acts as a visual indicator of the frequency of the vibrations produced by the rod. As the rod vibrates at the frequency of the AC mains, the bulb will flicker or light up in synchronization with the vibrations, providing a way to visually observe the frequency.
Why is it dangerous to pass to much current through the mains cable?
Current or AMPS are what the appliance draws or load of the appliance. So, if you have a say 10,000 amps going thru a cable rated for say 1,000 amps , guess what ,the cable over heats and either will melt or at least catch fire.
Which wire is the most dangerous in a plug?
The Active wire is always either Red (in a 3 core Red, Black and Green cable) or Brown (in a 3 core Brown, Blue and Green/Yellow cable). You can also be electrocuted by the neutral (Black or Blue) wire if the active is still supplying current through a device. The only truly safe way to handle mains wiring is to completely isolate the circuit at the fuse board.
What is the function of the power supply cable?
· A power cord, line cord or mains cable is known as the supply cable, which temporarily connects an appliance to the mains electricity supply to a wall socket. · A supply cable connects the refrigerator to the mains electricity supply via a wall socket.
What is the function of the power cables?
· A power cord, line cord or mains cable is known as the supply cable, which temporarily connects an appliance to the mains electricity supply to a wall socket. · A supply cable connects the refrigerator to the mains electricity supply via a wall socket.
What is the function of a mains lead in a strip heater?
The mains lead in a strip heater serves as the primary power supply connection between the heater and the electrical outlet. It is typically a flexible insulated cable that carries the electrical current from the source to the heating element within the heater. The mains lead is essential for providing the necessary power for the heater to generate heat and maintain the desired temperature. It is important to ensure that the mains lead is properly connected and in good condition to prevent any electrical hazards or malfunctions.
What is difference between battery and mains electricity?
Mains supply provides alternative current while battery provides direct current.
How many amps are in mains power?
In most countries, mains power typically supplies electricity at 120 or 240 volts. The current flowing through mains power can vary depending on the electrical load, but it is typically around 10-15 amps for household circuits.
What you get from mains voltage or current?
You get power, which is voltage * current (so both!).
What is service mains in power transmission system?
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
Why is mains electricity more dangerous than battary?
Two main reasons: - voltage - batteries usually(but not always) have such a low voltage that they can't push a dangerous current through a human body. - muscle interaction - Batteries are DC (direct current) while mains are AC (alternating current). And AC current will cause the muscles to spasm and lock, so if you were to accidentally grasp something electric, it'll be really hard to break free. But don't get this wrong. If you know what you're doing, it's entirely possible to kill yourself with nothing but a 12-volt battery.
What does 1.5mm and 2.5mm in mains cable refer to?
The 1.5mm and 2.5mm in mains cable refer to the cross-sectional area of the conductors, specifically the copper or aluminum wires within the cable. This measurement indicates the thickness of the wires, which affects the cable's current-carrying capacity and resistance. Generally, a larger cross-sectional area (like 2.5mm) can handle higher electrical loads safely compared to a smaller one (like 1.5mm). Therefore, the choice between these sizes depends on the electrical demands of the application.
What must be fitted to a cable of a radio before it can be connected to the mains electricity supply?
Before a radio can be connected to the mains electricity supply, a suitable plug must be fitted to the cable. This plug should be compatible with the electrical standards of the region, ensuring proper voltage and current ratings. Additionally, it's important that the plug has the necessary safety features, such as fuses, to protect against electrical faults.
