Hence volt a. Current will kill you but some amount of voltage is required to flow that current in the body breaking the human body resistance. In other words, an enough power is required to pass in the human body for proper electric shock. Voltage and amperage are two measures of electrical current or flow of electrons. An electrical current at 1, volts is no more deadly than a current at volts, but tiny changes in amperage can mean the difference between life and death when a person receives an electrical shock.
Amperage, the higher the amps the more damage Some amperages and their effects on the body: 1 milliamp is the perceptual level; 5 milliamps is a shock felt; milliamps is painful shock; milliamps can result in extreme pain, respiratory arrest, severe muscular contraction; amps results in ventricular ….
An electric shock from a volt power point can kill you, but on a dry day your car door can zap you with 10, volts and just make you swear. It is called electric shock. If the current flow continues Further, it damages the tissues of the body which leads to decrease in resistance of the body. It is the high current flowing in the body that cause much harm. The primary reason that power is transmitted at high voltages is to increase efficiency. As electricity is transmitted over long distances, there are inherent energy losses along the way.
The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. This translates to the capacity for greater work, which is the same thing as more power. Higher voltage also means less current to do the same amount of work, so longer battery life. The starting torque induces in the induction motor is also very low. Because of the following reasons the motor has poor efficiency. Thus, their designs are kept small, and the motor has low power ratings.
The shaded pole motor may have two or four poles. Here in this article, we use the two-pole motor for the sake of simplicity. The speed of the motor is inversely proportional to the number of poles used in the motor. Stator — The stator of the shaded pole motor has a salient pole.
The salient pole means the poles of the magnet are projected towards the armature of the motor. Each pole of the motor is excited by its exciting coil.
The copper rings shade the loops. The loops are known as the shading coil. The poles of the motor are laminated. Lamination means multiple layers of material are used for making the poles. So, that the strength of the pole increases.
As this type of motor is very simple of construction, they can be used in many places like small fans, Air conditioner, hair dryers, projectors etc. Thank you for visiting the website. You May Also Like:. When Capacitor store more Energy Series or Parallel connection?
