The resistor is a passive electrical component that creates resistance to electric current flow. It is measured in ohms and can be homemade using a pencil. To find the needed resistance value for a circuit, Ohm's law can be used with the voltage and current specifications. The colors of resistors can indicate their resistance values and resistor calculators online can help read these color codes. Common types of resistors include fixed resistors and variable resistors.

2. What is it?
 The resistor is a passive electrical component to create resistance in the flow
of electric current.
 The resistance is measured in ohms.
 Now We Will make Our Resistor with pencil.

3. How can get the resistance for the circuit?
We Can get it from the ohm’s law,
R=V/I
Ex:LED:45 mA
Battery:9V
