What is the correct method to find the fuse rating needed for a device? A) A = electrical power × potential difference B) A = potential difference / electrical power C) A = electrical power / potential difference D) A = 1 / electrical power
Understand the Problem
The question is asking for the correct formula to determine the fuse rating needed for a device based on electrical power and potential difference. We need to evaluate the provided options to identify which one is correct.
Answer
A = electrical power / potential difference
The correct method to find the fuse rating needed for a device is C) A = electrical power / potential difference.
Answer for screen readers
The correct method to find the fuse rating needed for a device is C) A = electrical power / potential difference.
More Information
To find the correct fuse rating, it's important to divide the electrical power (in Watts) by the potential difference (in Volts), which gives the current in Amps needed for the device.
Tips
A common mistake is to confuse the formula with other power and voltage relations, such as power calculation formulas. Ensuring the correct variables are on the right side of the equation is crucial.
