What is the mnemonic that represent every each of the colors code of the resistors?
|BBROYGBVGW||Bad Boys Race Our Young Girls But Violet Generally Wins (mnemonic for resistor color code)|
|BBROYGBVGW||Black Brown Red Orange Yellow Green Blue Violet Grey White (electronic resistor color code sequence)|
What is tolerance of a resistor?
Tolerance is the percentage of error in the resistor’s resistance, or how much more or less you can expect a resistor’s actual measured resistance to be from its stated resistance. A gold tolerance band is 5% tolerance, silver is 10%, and no band at all would mean a 20% tolerance.
How do you learn resistor color code?
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.
What is resistance color code?
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.
How do you remember which wire is hot?
Place the prong of the multimeter’s black wire on the bare metal on the end of a white wire, then read the meter. If you get a reading, the black wire is hot; if you don’t, the black wire isn’t hot.
What does 5 tolerance mean?
Tolerance Band Tolerance is the percentage of error in the resistor’s resistance, or how much more or less you can expect a resistor’s actual measured resistance to be from its stated resistance. A gold tolerance band is 5% tolerance, silver is 10%, and no band at all would mean a 20% tolerance.
What is TCR resistor?
One of the main specifications for precision resistors is the temperature coefficient of resistance (TCR), which is intended to determine a reversible shift of the resistance from its ohmic value (as measured at room temperature, e.g., 25°C) when operating at different temperatures within the working range.
