Resistor (10 pieces Pack)

Resistor (10 pieces Pack)Resistors are one of the most widely used components in electronic circuits – there are many different types of resistor available having different properties and used in different ways in different circuits. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.There are two main circuit symbols used for resistors. The oldest one is still widely used in North America and consists of a jagged line. The other symbol is a small rectangle, and this is often termed the international resistor symbol and it is more widely used in Europe and Asia. For fixed resistors there are different characteristics that need to be taken into account.   The unit or resistance is the Ohm, which is denoted by the Greek letter Omega: Ω and resistor values may be seen quoted in terms of Ohms – Ω, thousands of Ohms or kilohms – kΩ and millions of Ohms, megohms, MΩ.When written on circuits values like 10k may be seen meaning 10 kilohm, or 10 kΩ. The Omega sign is often omitted and the decimal point replaced by the multiplier: e.g. 1R5 would be 1.5 Ohms, 100R is 100Ω, 4k7 is 4.7 kΩ, 2M2 is 2.2MΩ and so forth.All other factors being equal, in a direct-current (DC) circuit, the current through a resistor is inversely proportional to its resistance, and directly proportional to the voltage across it. This is the well-known Ohm’s Law. In alternating-current (AC) circuits, this rule also applies as long as the resistor does not contain inductance or capacitance.Related video hereFor other types of resistors, click here Keep an eye on our website to avail the –resistor best price in BD (Bangladesh)
