What is an Electrical Connection?&

Concept of cut in voltage

An electrical connection is a type of structure that allows current to pass through it. A cable has connections between the feeder and motor. The electrical connection is made at the feeder end and at the motor terminal box end.

The electrical connections are given to the supply of power to the consumers. Without connections, there is no current flowing on the circuit. The circuit connections depend upon the different types of loads consumption.

Without electrical connections, the electrical equipment can not be operative. The power flow is possible with electrical connections of the equipment from the supply source.

Therefore, any equipment that uses electricity has a connection that leads to it from the outside. Inside the device are connections that lead to individual subsections of the system.

Types of Electrical connections

Basic interlocking cable

  • This type of connection widely used in almost every size, ranging from large to small and from simple to complex.
  • The interlocking cable transfers the energy from the source to load.
  • Power cord is the example of interlocking cable.
  • The more equipment can be connected at the output side of the interlocking cable by providing more power sockets.

Screw Connections

A screw connection has a bare wire placed into a threaded hole. The connection can be made by wounding down the screw with wire. It creates a tight connection between the wire and screw or the housing. This connection does not affect the vibration & other harsh conditions.

Capped Connections

The other type of electrical connection is capped ends. These connections simply have two bare wires wound together and then capped with an insulating plastic cap. This connection is easy to take apart so it is often used inside homes for things like mounted lights or electrical sockets. Since the connection isn’t directly fused or interlocked, these are typically only used in places where the wires won’t be bumped or allowed to come loose.

Concept of cut in voltage

In this post, we will discuss the concept of cut-in voltage. The forward voltage at which the diode starts conducting is called the cut-in voltage of the diode. At cut-in voltage, the diode conducts heavily. There is no linear relationship between voltage and current. In short, the diode exhibits non-linear characteristics.

The cut-in voltage of various didoes is different. The silicon & germanium diode have cut-in voltage 0.7 volts & 0.3 volts respectively.

The Schottky diode has a cut-in voltage of 0.15 V. The diode does not allow the current through it if the voltage is less than the specified cut-in voltage of the diode.

The most common function of the diode is to conduct in the forward direction and to remain cut-off during the reverse direction. Thus, the diode conducts only in the forward bias condition and blocks the current in the reverse bias condition. We can say the diode acts as a check valve.

What is cut-off voltage of battery?

In batteries, the cut-off voltage is the specified lower-limit voltage at which battery discharge needs to stop. The battery is out of charge when the battery voltage is equal to its cut-off voltage. The cut-off voltage is usually chosen so that the maximum useful capacity of the battery is achieved.
