Arrangement of Resistance for Conductors | Wiring | Electrical Engineering

The following points highlight the two main types of arrangement of resistance for conductors. The arrangements are: 1. Resistances in Series 2. Resistances in Parallel. Type # 1. Resistances in Series: When two or more conductors or coils or electrical appliances or resistors are joined together one after another to form a single circuit, they are said to be in [...]

Properties of Common Insulating Materials | Wiring | Electrical Engineering

An insulator is a substance possessing such enormous resistance that practically it does not permit electricity to flow through it. Electrons can be removed from the atom of any insulator with great difficulty. The outer electrons can be detached from their parent atoms when, in comparison with a conductor, considerably high amount of voltage is applied. Amongst the good insulators [...]

Conducting Materials of a Conductor | Wiring | Electrical Engineering

Every material offers a certain amount of opposition to the flow of electricity through it. Resistance may be defined in a general way as that property of a body which opposes the flow of electricity. A conductor is a substance of such small resistance that it readily allows electricity to flow through it. The best conductors Eire carbon and metals, [...]

Value of Alternating Current and EMF | Wiring | Electrical Engineering

In this article we will discuss how to determine effective value of alternating current and EMF, explained with the help of a suitable graph. In a graph plot the instantaneous values of current along the ordinate and the corresponding angular displacements along the abscissa for one complete cycle or 360°. A Sine curve will be obtained as shown in figure [...]

Leading Current from the Supply Line | Wiring | Electrical Engineering

The following devices take leading current from the supply line: 1. Static Capacitor or Condenser 2. Over-Excited Synchronous Motor 3. Phase Advancer. Device # 1. Static Capacitor or Condenser: Static capacitor takes a current which leads the applied voltage by about 90°. Thus, it acts in direct opposition to inductance, neutralizes the inductive influence of the circuit and improves the [...]

Calculating Power Factor in an A.C. Circuit | Electrical Engineering

The below mentioned article provides a formula for calculating power factor in the A.C. circuit. The power in watt absorbed by a d.c. circuit is known when the supply pressure in volt across the circuit is multiplied by the current in ampere flowing through the circuit. But in an a.c. circuit the product of supply pressure and the circuit current [...]

Use of Different Types of Switches | Accessories | Electrical Engineering

In this article we will discuss about the use of various types of switches for domestic and commercial purposes. Use of Single-Pole and Double-Pole Switches: A single-pole switch may be used in a circuit in which normally the current does not exceed 5 amperes. Where the current exceeds 5 amperes, the practice is to use a double-pole switch there. When [...]

Installation of Cleat Wiring | Systems | Wiring | Electrical Engineering

Conductors should be visible all throughout a cleat wiring. In temporary installations wiring is often done over bobbin or knob insulators in place of cleats. Whenever the wires pass through a floor or through a space where some damage is apprehended, they should be provided with an additional protection of a special strong covering up to a height of 1.5 [...]
