A circuit breaker may need to switch short circuit currents as high as <u>fifteen (15)</u> times its rated current.
<u>Rated current</u> is basically the<u> maximum limiting current</u>. If the current exceeds its maximum limit, there will be overheating and, in severe circumstances, a <u>short circuit</u> will result.
A<u> circuit breaker</u> is a type of <u>electrical safety</u> device used to guard against short circuit damage to an electrical circuit.
An example of circuit breakers that are most frequently used in low voltage circuits is <u>Miniature Circuit Breakers</u> (MCBs).
These are the switches that automatically turn off when the current in a circuit exceeds the<u> safe limit</u>.
So, to ensure complete protection against <u>short circuits</u> & <u>overloading</u>, a circuit breaker may need to switch short circuit current as high as fifteen times its rated current.

Hi low ok kyuh a asterion and coment
The crystal of potassium chloride has a definite shape because it consists of particles that are held in fixed positions.
Ionic solids are crystalline in nature. This means that the ions that compose them are arranged in an orderly manner to form a crystal lattice.
This crystal lattice is composed of a regular repeating pattern called the unit cell. The ions in these unit cells are held together by strong electrostatic forces.
Hence, the crystal of potassium chloride has a definite shape because it consists of particles that are held in fixed positions.

Answer:
0.434 m
Explanation:
We are given that
Mass per unit length=
1 kg=1000 g
Tension=350 N
Fundamental frequency=f=440 Hz
We have to find the length you should make it.
We know that
Using the formula
l=0.434 m
Hence, you should make it 0.434 m long.
