Resistor oppoeses or stops the current flow from the circuit.
Ohms is the units of the resistance.
by ohms law resistance equal to voltage to current ratio.
Resistor was made for the protection of the circuit from high voltages or fluctuations.
resistors value is measured by colour coding of the resistor or by the multimeter.
These resistors are mostly used in all the circuits for protection of the circuit.
Resistor containce the nichrome wire wounded around it.
Resistors are cheaply available in the market.
Even a small wire will have some resistance.
