• Since R is constant, Eq.(1) is the equation of a straight line. For this reason, the resistor is called a linear resistor. A graph of u(t) versus i(t) for a linear resistor is a line passing through the origin with a slope of R. • Resistors whose resistances do not remain constant for different terminal current are known as 5 resistors. For such a resistor, the resistance is a function of the current flowing in the device. In reality, all practical resistors are nonlinear because the electrical characteristics of all conductors are affected by environmental factors such as temperature. Many materials, however, closely approximate an ideal linear resistor over a desired operating region.

• The effective value of voltage and current is the common method of expressing the Value of AC. This is also known as the RMS value. The effective value of AC is defined in terms of an equivalent heating effect when compared to DC. One RMS ampere of current flowing through a resistance will produce heat at the same rate as a DC ampere. For purpose of circuit design, the peak value may also be needed. For example, insulation must be designed to withstand the peak value, not just the effective value. It may be that only the effective value is known. To calculate the peak value, multiply the effective value by 1.41.

The circuit element used to model the current-resisting behavior of a material is the 1 . It is the simplest 2 element. George Simon Ohm is credited with formulating the 3 relationship for a resistor based on experiments performed in 1826. This relationship is known as Ohm's Law. Ohm's Law states that the voltage across a resistor is 4 the current flowing through the resistor. The constant of proportionality is the resistance value of the resistor in ohms. The circuit symbol for the resistor is shown in Fig.1. For the current and voltage shown, Ohm's Law is u(t) = Ri(t) (1) where R≥0 is the resistance in ohms.

• Inductors react against changes in current by dropping voltage in the polarity necessary to oppose the change. When an inductor is faced with an increasing current, it acts as a load: dropping voltage as it absorbs energy (negative on the current entry side and positive on the current exit side, like a resistor). The ability of an inductor to store energy in the form of a magnetic field (and consequently to oppose changes in current) is called inductance. It is measured in the unit of the Henry (H). • Inductors used to be commonly known by another term: choke. In large power applications, they are sometimes referred to as reactors.

• Capacitors react against changes in voltage by supplying or drawing current in the direction necessary to oppose the change. When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it absorbs energy (current going in the negative side and out the positive side, like a resistor). When a capacitor is faced with a decreasing voltage, it acts as a source: supplying current as it releases stored energy (current going out the negative side and in the positive side, like a battery). The ability of a capacitor to store energy in the form of an electric field (and consequently to oppose changes in voltage) is called capacitance. It is measured in the unit of the Farad (F). Capacitors used to be commonly known by another term: condenser

• The conveyance1 of electric power from a generating station2 to consumers is known as electric power system. The electric power network is the part of the electric power system but the generators3 and the consumers, including substations4, transmission lines, and distribution networks5. • The function of an electric power network is to connect the generating stations with the customers and with the minimum disturbance6 to transfer this power over transmission lines and distribution networks with the maximum efficiency7 and reliability8 for delivery to consumers at virtually fixed voltage and frequency. Electric power systems are designed to provide consumers with electrical energy of a certain standard or quality.
