What are the advantages and Disadvantages of using Circuit Breakers Instead of Fuses

Physics

Inessa [10]2 years ago

Answer:

The benefits are defined throughout the section described according to the particular context.

Explanation:

  • Just before it completes its function, users should substitute a fuse, although circuit breakers work through a trigger where you essentially restart or reboot.
  • Fuses become composed of such a lump of material (metal) that can explode when enough electric current is passed through everything, disturbing another circuit successfully therefore stopping the equipment from hitting another power outage.

Answer:

Explanation:

Circuit breaker is an automatic electrical  switch which cuts the power when there is surge in current.

Advantages of Circuit breaker

  • They are more reliable i.e. they are not replaced frequently
  • Efficient and easy to safeguard electrical appliance

Disadvantage of Circuit breaker

  • They are less sensitive than fuses i.e. fuses are much faster than circuit breaker.

Define light yearend explain how and why light years are used to measure distances in the universe
yan [13]
Light years are the distance light can travel in a full year. They are used because there are really big distances in the universe that are easier to measure with a really large form of measurement (light years).

When you take your 1900-kg car out for a spin, you go around a corner of radius 55 m with a speed of 15 m/s. The coefficient of
pentagon [3]

Answer:

7772.72N

Explanation:

When u draw your FBD, you realize you have 3 forces (ignore the force the car produces), gravity, normal force and static friction. You also realize that gravity and normal force are in our out of the page  (drawn with a frame of reference above the car). So that leaves you with static friction in the centripetal direction.

Now which direction is the static friction, assume that it is pointing inward so

Fc=Fs=mv²/r=1900*15²/55=427500/55=7772.72N

Since the car is not skidding we do not have kinetic friction so there can only be static friction. One reason we do not use μFn is because that is the formula for maximum static friction, and the problem does not state there is maximum static friction.

Calculate the distance traveled by a projectile as a function of launch angle. Compare the distances for two projectiles launche
DaniilM [7]

Answer:

R = x_{max} = \frac{v^2\sin(2\theta)}{g}\\\frac{R_1}{R_2} = \frac{\sin(2\theta_1}{\sin(2\theta_2}

Explanation:

Using kinematics equations:

\Delta x = v_{0x}t\\\Delta y = -\frac{1}{2}gt^2+v_{0y}t

Use \Delta y = 0 due to condition of distance traveled.

Solving second equation for time, there are two solutions. t=0 and

t=\frac{2v_{0y}}{g}

Use the expression in the first equation to have

R = \frac{2v^2 \cos\theta\sin\theta}{g}

Using trigonometric identities, you have the answer of the distance.

By doing the ratio for two different angles, you have the second answer. Due to sine function properties, the distances can be the same to complementary angles. Example, for 20° and 70°, the distance is the same.
