What else can I help you with?
Why is there a positive and negative terminal in electical device?
there are positive and negative terminal in electrical device who operate on dc power supply because they wont work if the connection is reversed. but devices who operate on ac usually dosenot have polarity marks .
What activities are lost when the electrical supply is cut off?
All activity that depends upon an electrical supply to operate will cease. To overcome this type of situation standby generators and uninterrupted power supplies are used until the electrical supply is re-established.
On which current does fan rotate?
Most fans operate on an alternating current (AC) as it is the standard electrical power supply in homes and buildings. However, some fans, like those in vehicles or powered by batteries, may operate on direct current (DC).
Can I connect a 240v contactor to 110v?
You can connect a 240V contactor to a 110V supply, but it may not function properly or safely. The contactor may not activate as intended since it is designed to operate at a higher voltage, potentially leading to overheating or damage. It's crucial to use a contactor rated for the voltage you plan to supply to ensure safe and effective operation. Always consult a professional electrician for guidance on electrical installations.
What are the functions of charging system?
The main function of the charging system is to generate electrical power to recharge the vehicle's battery while the engine is running. It also provides power to operate electrical components in the vehicle and ensures a consistent voltage supply. Additionally, it regulates the voltage to prevent overcharging of the battery.
What does 500-1000mA input means?
A 500-1000mA input specification indicates that the device requires a current supply within that range to function properly. This means it can operate with a minimum of 500 milliamps and a maximum of 1000 milliamps. If the current supplied is below 500mA, the device may not work effectively, while exceeding 1000mA could potentially damage it. This specification is important for ensuring compatibility with power sources.
Why does proper starter operation depend on good battery cables and connectors?
A starter is an electrical device that requires the proper supply of electricity to operate properly. Weak battery or loose or corroded connections and it will not function properly.
Can you use 5v 1000ma adapter on a 45v 400ma device?
No you can not. The power supply output of 5 volts is under sized. There is no way that a 45 volt device would operate from it. You will need to find a power supply of 45 volts.
Why is there a positive and negative terminal in electical device?
there are positive and negative terminal in electrical device who operate on dc power supply because they wont work if the connection is reversed. but devices who operate on ac usually dosenot have polarity marks .
What is the purpose of a toilet shutoff valve and how do you properly operate it?
The purpose of a toilet shutoff valve is to control the flow of water to the toilet. To properly operate it, turn the valve clockwise to shut off the water supply and counterclockwise to turn it back on.
How should I properly wire the disconnect box for my electrical system?
To properly wire the disconnect box for your electrical system, follow these steps: Turn off the power supply to the electrical system. Connect the incoming power supply wires to the line side of the disconnect switch. Connect the wires leading to the electrical system to the load side of the disconnect switch. Make sure all connections are secure and properly insulated. Turn on the power supply and test the disconnect box to ensure it is functioning correctly.
Will a 15DC 1000mA power supply work on a device needing 15DC 1500mA power supply?
Your question is confusing, but if you are asking whether you can use a 9V/250 mA adapter to supply a load device rated at 5 V/1000 mA, then the rule is quite straightforward. The adapter's rated output voltage must match that of the intended load, but its rated current must exceed that of the load. So in your example, you cannot use the adapter with the intended load.
What activities are lost when the electrical supply is cut off?
All activity that depends upon an electrical supply to operate will cease. To overcome this type of situation standby generators and uninterrupted power supplies are used until the electrical supply is re-established.
What is the function of the toilet shut off valve and how do you properly operate it?
The function of the toilet shut off valve is to control the flow of water to the toilet. To properly operate it, turn the valve clockwise to shut off the water supply and counterclockwise to turn it back on.
What happens when a solar cell cannot supply enough current to a circuit?
the circuit might not operate properly. but shouldn't effect the circuits them self.
How do the milliamp ratings of LEDs 20ma and a 12 volt 1000ma power supply figure into the resistor equations or do they not?
A: Since you know the current flow you need the voltage drop for this particular led at 20ma. All LED require a current and voltage to operate properly assuming a voltage drop of 2v then for a 12v source it becomes 12-2=10v 10v/.02=500 ohms in series to limit the current is required
What is the purpose of a bathroom sink shut off valve and how do you properly operate it?
The purpose of a bathroom sink shut off valve is to control the flow of water to the sink. To properly operate it, turn the valve clockwise to shut off the water supply and counterclockwise to turn it back on.
