The metal film resistor happens to be a lot more accurate, but anyhow, we’re not going to worry about this. Here is an image of two resistors, they’re made of a different material but they’re both resistors, for the most part, they work exactly the same.
You can remember the colors order by remembering the following line. You will be able to read a resistor with a single glance, of course, if you remember the resistor color chart. If you know the method of reading a 4 band resistor or 5 band resistors then you won’t need a multimeter. If we increase the resistance, the current will reduce.Resistor Color Codes- One of the first things, you want to try to understand to get familiar with, when you’re learning electronics is the resistor color codes.If we increase the voltage, the current will increase.Since the current is set by the values of the voltage and resistance, the Ohm's law formula can show that:
The resistance (R) in ohms (Ω) is equal to the voltage in volts (V) divided by the current I in amps (I): Resistance calculation: When we know the voltage and the current, we can calculate the resistance. The voltage V in volts (V) is equal to the to the current I in amps (I) times the resistance (R) in ohms (Ω): Voltage calculation: When we know the current and resistance, we can calculate the voltage. Ohm's law definition The resistor's current I in amps (I) is equal to the resistor's voltage VR=V in volts (V) divided by the resistance 9R) in ohms (Ω): With water flow analogy we can imagine the electric current as water current through pipe, the resistor as a thin pipe that limits the water flow, the voltage as height difference of the water that enables the water flow. The resistor's voltage drop and resistance set the DC current flow through the resistor. Ohm's law defines a linear relationship between the voltage and the current in an electrical circuit.
