How do I figure out a 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..
What is measured in Ohm?
The ohm (symbol: Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm.

How do you read resistance color codes?
Always read resistors from left to right. – Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.
How does a diode behave in a circuit?
The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking it in the opposite direction (the reverse direction). … These techniques are used to create special-purpose diodes that perform many different functions.
What does a diode look like?
A diode looks like a two terminal small devi ce. It is usually black in colour and has a mark on it to distinguish its p or n side according to biasing.
What is color code resistance?
Resistor Color Coding uses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating. … The colors brown, red, green, blue, and violet are used as tolerance codes on 5-band resistors only.
What is Colour code?
A color code or colour code is a system for displaying information by using different colors. The earliest examples of color codes in use are for long distance communication by use of flags, as in semaphore communication. … Color codes do present some potential problems.
What color is a 1 ohm resistor?
For 1 ohm carbon resistor colour will be Brown followed by the colour for it’s given tolerance i.e 5% for Gold 10% for Silver and 20% for no band.

How do you read a diode?
A diode is reverse-biased when the positive (red) test lead is on the cathode and the negative (black) test lead is on the anode. The reverse-biased resistance of a good diode displays OL on a multimeter. The diode is bad if readings are the same in both directions.
