Resistance
What is resistor Resistor is an electrical component that reduces the electric current. The resistor's ability to reduce the current is called resistance and is measured in units of ohms (symbol: Ω). If we make an analogy to water flow through pipes, the resistor is a thin pipe that reduces the water flow. Ohm's law The resistor's current I in amps (A) is equal to the resistor's voltage V in volts (V) divided by the resistance R in ohms (Ω): The resistor's power consumption P in watts (W) is equal to the resistor's current I in amps (A) times the resistor's voltage V in volts (V): P = I × V The resistor's power consumption P in watts (W) is equal to the square value of the resistor's current I in amps (A) times the resistor's resistance R in ohms (Ω): P = I 2 × R The resistor's power consumption P in watts (W) is equal to the square value of the resistor's voltage V in volts (V) divided by the resistor's r
