What else can I help you with?
What do you think would happen to the winding if the current were sustained for a few minutes?
Will damage
What is the medium voltage of circuit breaker?
low is below 600V medium 600 to 2500V High above 2500V usually medium and high voltage equipment is called switchgear the current is monitored and 3 shorts within 10 minutes will open the switch overloads are usually 200% for over 20 minutes but the big stuff is programable
Calculate the total number of electrons flowing through a circuit in 20 minutes and 40 seconds if a current of 40 mA flows through the circuit?
The current in a circuit is a measure of passing electrical charge per second. Each electron carries a fix amount of charge. Therefore the number of charge moving depends on the speed of the charge, in this case electrons. In conductors like copper, there are just so many free electrons that they move in bulk slower than snail. The the Cathode ray tube, the speed is at a fraction of speed of light, not many electrons are flying. For actual number, look up speed of electron in copper at room temperature, and multiple the electrical charge constant to get at the current. This must be a standard class tutorial.
What is the value of the current of a ten ohm resistor which has a constant current and 1200 C of charge flowing through it in 4 minutes?
5 A Q / t = I so 1200/4*60 = 5 A
How much work can be done by an electric motor that is plugged into a wall of 120V if 0.75 amps of current flow through it for 2 minutes?
120 V x 0.75 A = 90 watts2 minutes = 120 seconds90 watts for 2 minutes = (90) x (120) = 10,800 watt-seconds = 10,800 joulesThe motor consumes 10,800 joules of electrical energy during that 2 minutes.If the motor is perfectly (100%) efficient, then that's the amount of work youcan get out of it.In the general case, the amouunt of work the motor can do is (10,800 joules) x the motor's efficiency.
An electric bulb draws a current of 0.25A for 20 minutes calculate the electric charge?
1 Ampere = 1 Coulomb per second0.25 A = 0.25 Coulomb per sec1 minute = 60 seconds20 minutes = (20 x 60) = 1,200 seconds0.25 A for 20 minutes = (0.25 x 1,200) = 300 Amp-seconds = 300 Coulombs of charge
Calculate the charge transferred in 25 minutes by a current of 500 mA?
The charge transferred in 25 minutes by a current of 500 mA is 750 coulombs. Amperes is defined as coulombs per second, so 500 mA is 0.5 coulombs per second. 25 minutes is 1500 seconds, so the charge is 750 coulombs.
When a light bulb has 1100 C of electrical charge flow through it in 8 minutes what is the electric current in amperes?
Use the equation I=q/t, where I is amperes, q is coulombs and t is time in seconds.First you have to convert the minutes to seconds, so 60 x 8= 480 seconds. ThenI=1100/480. I = 2.29 amperes.
What is the quantity of charge that passes through a conductor when there is a current of 0.25 A for 10 minutes?
1 A = 1 coulomb per second(0.25 coulomb/sec) x (10 minutes) x (60 sec/min) = 150 coulombs
How many coulombs of charge pass through a cell if 2.40 amperes of current are passed through the cell for 85.o minutes?
To calculate the total charge passing through the cell, use the formula Q = I * t, where Q is the charge in coulombs, I is the current in amperes, and t is the time in seconds. First, convert 85.0 minutes to seconds: 85.0 minutes * 60 seconds/minute = 5100 seconds. Then, plug in the values: Q = 2.40 amperes * 5100 seconds = 12240 coulombs.
Why does the circuit breaker trip after 30 minutes?
The circuit breaker trips after 30 minutes because it is designed to protect the electrical system from overheating and potential damage due to prolonged high current flow.
How does MCCB circuit breaker work?
A Miniature Circuit Breaker or "MCB" works as a normal electrical circuit breaker but is a much smaller device. As well as electro-mechanical relay technology it includes electronic circuitry to achieve its small overall size. MCBs are now used extensively for consumer power-distribution panels and inside small electrical equipment.For more information see the answers to the Related Questions and also the Related link shown below.
How long should you wait before opening a monitor case to replace the fuse?
At least 60 minutes because they contain capacitors which hold electric current.
How do I reset an electric water heater?
To reset an electric water heater, locate the reset button on the thermostat and press it. Wait a few minutes for the heater to restart. If the problem persists, check the circuit breaker and ensure it is on. If the issue continues, contact a professional for assistance.
How many minutes does a 45mah battery last?
That completely depends on how much current is used by the circuit or device that's connected to the battery. For example, if there is no circuit or device connected to the battery, and no current is used, then the battery lasts for quite a long time. But if you lay a screwdriver across the battery terminals and create great balls of fire, then the charge on the battery may only last for 1/2 second.
Whirlpool imperial series electric dryer which will no longer dry starting at 70 minutes. We have to begin at 55 minutes. Then it will dry for 55 minutes. What is the problem?
15 minutes.
How long does it take for 45 mL of water to boil on high?
It depends. Do you have a gas or electric stove. If you have electric about 2-3 minutes. If you have a gas stove about 4 minutes. Hope this answers your question
