## What is a "resistor"?

Resistors are electrical components or electronic components, the flow of electrical current element, a resistor having a certain impedance circuit can regulate the magnitude of the current and voltage.

Resistive impedance to electrical current flow will produce suppression, resulting in a voltage drop (voltage drop). Resistors are widely used in electrical and electronic circuit design.

Resistors can be divided to provide fixed resistors, variable resistors, slide resistance, a sliding rheostat sliding resistor or adjustable resistor. Usually refers to the adjustable resistor rheostat or potentiometer. Resistance value expressed in ohms, symbol Ω.

In electrical or electronic circuit design, the resistor may be constructed of a known voltage drop or current - voltage relationship. If the circuit, the current is known (current measurement amperes A), the resistor can be used to create electrical potential difference (voltage difference), the potential difference and current proportional to a known. In contrast, in the circuit, if the two nodes of the voltage drop (potential difference) is known, the resistor can be used to create a known current, and a current proportional to the potential difference.

Attenuator (Attenuator), is a network of two or more resistance by the resistor composition, also known as a voltage divider.

T erminating resistor (Line Terminator), it is a special package resistance or resistance block, used to ensure the stability of the whole circuit signals.

The role of terminal resistance as filters to eliminate electrical noise from a number of cables and equipment produced.

What is "Ohm's Law"?

Resistance - ohms (Ω), voltage - volts (V), current - ampere (A), Power - Watts (W) relationship table formula

Resistance - ohms (Ω), voltage - volts (V), current - ampere (A), Power - Watts (W) relationship table formula

Ohm's law is a simple formula to display the impedance, voltage, and current flows through the wire of the relationship, or other types of resistive material. In mathematics, Ohm's law can be written as:

I = V / R,

I current (Amps),

V voltage (Volts),

R Impedance (Ω).

Ohm's law can also show the relationship between voltage and power, using the following equation:

P = V 2 / R,

P Power (Watts),

V voltage (Volts),

R Impedance (Ω).
