Type your answer here... u can c colored rings on resistor . The color of these rings is the key, follow a simple rule " Bad Boys Ravish Young Girls But Verginia Goes Willingly"
initial letter of each word mentioned in above phrase represents a color & their sequence no. represents numerical value of that color ring.
The color bands on a resistor indicate its resistance value. Each color corresponds to a digit, which is used to calculate the resistance value based on a specific color code chart. The tolerance of the resistor is also indicated by a separate color band.
There are many colours for resistor rings but the reason that we have them is to help the resistor reduce the electrical current that is passing through.
yes you can! you can use a multimeter and a resistor.
how calcualte conductivity
The colored bands on a resistor represent the resistor value and tolerance. The first two bands indicate the significant digits of the resistance value, the third band represents the multiplier, and the fourth band (if present) indicates the tolerance of the resistor. By decoding these colors, you can determine the resistance value of the resistor.
You can only use a resistor to drop a voltage at a constant current. If you know the current, use Ohm's law to calculate the resistor value.
p=I*I*R ,P=V*V/R;where I is the current passing through the resistor, and V is the voltage across resistor, and R is the Resistance of the resistor,
in simple terms, band represent numbers, ex:- 10K resistor have different colour code and that is difference from 5k resistor. if you type in google 'resistor colour code' that will describe how to calculate a resistor value. thanks
A resistor by itself has no time constant. For a circuit to have a time constant it must contain either capacitors or inductors.
A rheostat is simply a variable resistor used to control current. It does not have a positive or a negative terminal.
To find the current through the 40 ohm resistor, first calculate the total resistance of the parallel circuit: 1/Rt = 1/120 + 1/60 + 1/40. Then, calculate the total current using Ohm's Law, I = V/Rt. Finally, use the current divider rule to find the current passing through the 40 ohm resistor.
The minimum and maximum possible value is defined by the tolerance. To calculate the range of the resistor, simply add or remove the amount of the tolerance. For example, a 100Kohm resistor with 5% tolerance can range from 95Kohm through until 105Kohm. The lower the tolerance, the more accurate the resistor is.
