RESISTOR COMPUTATION

RESISTOR

Whats is a resistor?

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.

To calculate a four band resistor value, use the middle four "drop" boxes then click on the "Calc 4 Band" button. For a five or six band resistor, you can use all six boxes but all 6 do not necessarily have to be used - the "Temperature Coefficient" box, for example.

How do you find the value of a resistor?

Steps

Read the color sequence that must be decoded to determine resistance. ...
Determine the coded number for the resistive value. ...
Determine the tolerance of the resistor. ...
Determine the decoded number for the resistive value.

How do you calculate resistor color code?

Calculating Resistor Values. For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.

How do you read a 5 band resistor?

Always read resistors from left to right. Resistors never start with a metallic bandon the left. If you have a resistor with a gold or silver band on one end, you have a5% or 10% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.

How do you calculate the tolerance of a resistor?

For the third resistor, we'll perform the calculation in an alternative way. First find the “nominal resistance,” or 470K in this case. Take the nominal value and multiply it by 1 + your tolerance, which is (1+0.1). Then take the nominal value and multiply it by 1 – tolerance, or (1-0.1).

How do I calculate current?

The current can be found from Ohm's Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated. The first step, then, is to find the resistance of the wire: L is the length, 1.60 m.

What is the formula of work?

The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.
