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.
An electric heater draws a current of 5 amps and its element has resistance of 50 ohms - if it's switched on for 5 minutes calculate the energy in kilo joule?
First, calculate the power of the electric heater using the formula P = I^2 * R, where I is the current and R is the resistance. P = 5^2 * 50 = 1250 watts. Convert the time from minutes to hours: 5 minutes = 5/60 hours = 1/12 hours. Calculate the energy used by the electric heater using the formula E = P * t, where t is the time in hours. E = 1250 * (1/12) = 104.17 watt-hours. Convert the energy to kilojoules by dividing by 3600 (since 1 watt-hour is equal to 3600 joules): 104.17 / 3600 = 0.029 kilojoules.
Fastest 3.1 mile run?
The current world record for the fastest 3.1 mile run (5K) is 12 minutes and 37 seconds, set by Joshua Cheptegei of Uganda in 2020.
How much work can a 500 watt electric mixer do in 2.50 minutes?
The work done by an electric mixer can be calculated by multiplying the power (500 watts) by the time (2.50 minutes) in seconds. First, convert the time to seconds: 2.50 minutes = 150 seconds. Then, calculate the work done: Work = Power x Time = 500 watts x 150 seconds = 75,000 joules.
Can electric company shut of power because the digital meter keeps breaking?
they must shut off the power to replace the meter this takes under 5 minutes if you are at the far end of a line you get lots of spikes and glitches and the digital meter is probably a bad idea it is the companys problem to give you the power you pay them for if it noisy and poor quality they should fix the problem, or use an analog meter that doesnt notice the trouble
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.
If a current of 32 amps is maintained for 2 min what quantity of ele ticity would be conveyed?
A current of 32 amperes for 2 minutes represents a current flow of 3,840 coulombs.One ampere is one coulomb per second.
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.
A current of 2A passes through 12V electric bulb . The electrical energy consumed by the bulb in 20 min is?
Assuming that you're truly running the bulb with 12 volts . . .(2 amperes) x (12 volts) = 24 watts = 24 joules per second(24 joules/second) x (60 seconds/minute) x (20 minutes) = 28,800 joulesAlso, in electric-bill terms ... 0.008 kilowatt-hour
A microwave oven uses a 115 V ran for 15 minutes how much electrical energy would it use?
Not enough information. To get the amount of electrical energy, you need to multiply the power used (in Watts) by the time (in seconds). The power used is not equal to the voltage; it is volts x amperes. Look for a metal sticker that shows the electrical characteristics of the device; it should show the amount of Watts used. If it only shows Volts and Amperes, multiply both to get the amount of Watts. (Technically there is also a power factor, but that can often be ignored.)
How many hours and minutes is in 233?
233 is just a dimensionless number. There are no hours, minutes,light-years, amperes, kilograms, or anything else in it.
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 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 much does an electrical engineer make an hour?
60 minutes
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.
