In summary, Maximum Allowable Current (MAC) is the maximum amount of electric current that a circuit or device can safely handle without causing damage. It is important to have a (+/-) 2% margin for MAC to account for small errors and fluctuations in current. MAC is calculated taking into consideration the maximum voltage and resistance of the circuit/device, as well as safety guidelines. While MAC can be exceeded in certain situations, it can lead to damage or failure if it happens frequently or for extended periods of time. The MAC can be increased by using higher quality materials, improving design and construction, and implementing safety measures.

Maxium Allowable Current to (+/-) 2% ?

Homework Statement



An experiment on the Earth's magnetic field is being carried out 7.00 from an electric cable.
What is the maximum allowable current in the cable if the experiment is to be accurate to 2.0 ? Assume that Earth’s magnetic field is .


Homework Equations



B = [I*μ]/[2*Pi*d]

The Attempt at a Solution



Check the picture to see how far I've gotten, but it's still wrong. I'm not sure how to attempt this problem.

you have to use 1750 * 2.0%

1750 * 0.02 = 35 A
 

FAQ: Maxium Allowable Current to (+/-) 2% ?

What is the definition of Maximum Allowable Current?

Maximum Allowable Current (MAC) refers to the maximum amount of electric current that a particular circuit or device can safely handle without causing damage or failure.

Why is it important to have a (+/-) 2% margin for Maximum Allowable Current?

A (+/-) 2% margin for Maximum Allowable Current is important because it allows for a small margin of error and ensures that the current does not exceed the safe limit. This margin also accounts for any fluctuations in the current due to external factors.

How is Maximum Allowable Current calculated?

Maximum Allowable Current is calculated by taking into account the maximum voltage and resistance of a circuit or device, as well as any safety factors or guidelines set by regulatory agencies.

Can Maximum Allowable Current be exceeded in certain situations?

In certain situations, such as power surges or short circuits, the Maximum Allowable Current may be exceeded temporarily. However, if this occurs frequently or for extended periods of time, it can lead to damage or failure of the circuit or device.

How can Maximum Allowable Current be increased?

The Maximum Allowable Current can be increased by using higher quality materials and components, improving the design and construction of the circuit or device, and implementing safety measures such as fuses or circuit breakers.
