The forward voltage is the voltage required to make an LED on, and it is usually between 1.7 V to 3.4 V, depending on the color of the LED lights. The maximum forward current is the continuous current flowing through the LED, and it is usually around 20 mA for basic LEDs. Now, we ...

It is a device that runs a fan to keep the air moving in a car’s ventilation system. To control the speed of the fan, use a blower resistor. The resistor is in series with the blower fan to regulate the electric current going through a motor. It usually has several resistors, and ...
For example, 2 nA bias current flowing through the 10 Ω resistor produces a 0.02 μV error referred to the input. Sign in to download full-size image Figure 4.2.2. Measuring input offset voltage. As simple as it looks, this circuit may give inaccurate results. The largest potential ...
You often need to control or monitor a power supply current of a few amps with the minimum possible voltage drop, for power efficiency reasons; a low value resistor of, say 10 mΩ will develop 50 mV when 5 A is passed through it and this can be amplified by a precision differential ...

resistance is measured in ohms (Ω). An ohm is the resistance that occurs when a current of one ampere (A) passes through a resistor with a one volt (V) drop across its terminals. The current is proportional to the voltage across the terminal ends. This ratio is represented byOhm’s ...
A current limiting resistor is a resistor used to reduce the current present in a circuit. A simple example is a resistor in series with an LED to limit the current control through it. This can set the intensity of the light generated and prevent the LED from exceeding its current limit ...
(1)Connect an uncertain signal to the ground GND through a resistor and fix it at a low level. (2)Pull-down is the output current from the device. (3)When an IO port with a pull-down resistor is set to the input state, it is normally at low level. ...
