How does a switch control an electric device?

A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'on' position, the circuit wire join and the circuit gets completed.


What is meant by max absorbed current?

Max absorbed current refers to the highest amount of electric current that a device, circuit, or system can draw from a power source without exceeding its specified limits or causing damage. It is an important parameter in electrical engineering, as it helps ensure that components operate safely and efficiently within their designed capacity. Exceeding this limit can lead to overheating, failure, or reduced lifespan of the device.


Rupturing capacity of a circuit breaker?

the maximum short current that can be safely break by the circuit breaker.


What is the length of time that a motor can safely run on starting and full load current?

It depends on the insulation provided in winding, motor can safely run on full load current. and over that it may burn but depends on cooling system of the motor. Motor can burn if insulation fails, failure of insulation depends on only the temperature rise.


Why Short circuits cause fire?

Because a short allows/causes very large current flow, which "overloads" the wire [conductor]. When a conductor [wire] carries much more current than is safely capable, then the conductor heats up, and can cause enough heat to ignite the insulation and adjacent combustible materials on fire.

Does the gauge of a wire change the amount the energy it carries?

It determines the amount of electric current it can safely carry


What is the difference between electronic current and conventional current?

Difference between conventional current and electric current? • Electric current can be either negative or positive, but conventional current is always positive.• The conventional current for an electron flow is positive, whereas the electrical current is negative.• For a flow of positive charges, both the electric current and the conventional current are the same.• Since almost every electrical circuit uses an electron flow, it can be safely stated that the conventional current = - electrical current.• In conventional current, the flow of electrons is assumed as a flow of protons on the opposite direction.


How do you cut an electric socket safely?

If you are not talking literally about cutting a socket and are referring about the sockets circuit, then all that needs to happen is, a switch needs to be cut into the circuit.


How does the electric igniter for a gas stove work to safely and efficiently ignite the gas for cooking?

The electric igniter for a gas stove works by creating a spark that ignites the gas when the stove is turned on. This spark is produced by an electrical current passing through a metal component, which then ignites the gas to safely and efficiently start the cooking process.


When seawater is decomposed what toxic gas is produced?

When seawater is decomposed, toxic chlorine gas can be produced. This can happen when an electric current is passed through seawater during the process of electrolysis. It is important to handle and dispose of chlorine gas safely due to its toxic properties.


How can I safely and effectively perform an electric cord repair?

To safely and effectively perform an electric cord repair, first unplug the cord and inspect it for damage. Cut out the damaged section and strip the insulation from the wires. Twist the matching wires together and cover them with electrical tape or use a wire connector. Finally, test the cord before using it again to ensure it is working properly and safely.


How can I safely fly with an electric razor in my carry-on luggage?

To safely fly with an electric razor in your carry-on luggage, make sure it is charged and turned off before packing it. Place it in a clear plastic bag and remove it during security screening. Follow TSA guidelines and regulations for electronic devices to avoid any issues during your flight.


What is Primary Current?

Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.


Is alternating current dangerous to humans and how can it be safely managed?

Yes, alternating current (AC) can be dangerous to humans, as it can cause electric shock and serious injuries. To safely manage AC, it is important to use proper insulation and grounding in electrical systems, follow safety guidelines when working with electricity, and avoid contact with live wires or electrical appliances. Additionally, using circuit breakers and ground fault circuit interrupters (GFCIs) can help prevent accidents and protect against electric shocks.


What is the maximum current rating for a wire that can safely handle 10 wire amps?

The maximum current rating for a wire that can safely handle 10 wire amps is 10 amps.

What is the purpose of an earth wire in electrical systems?

The purpose of an earth wire in electrical systems is to provide a path for excess electrical current to safely flow into the ground, preventing electric shocks and reducing the risk of fire.
