Forward Bias

Forward bias refers to a condition in electronic devices, particularly diodes, where the voltage applied allows current to flow easily. Imagine a one-way street: when traffic flows in the intended direction, everything works smoothly. In a forward-biased diode, applying positive voltage to the anode (front) and negative to the cathode (back) enables the flow of electrical current. This is essential for powering devices, as it allows electricity to pass through components when intended, ensuring the device functions correctly. Conversely, if the voltage is reversed, the diode blocks current, akin to traffic being stopped on a one-way street.
