hello everyone,
is this definition correct?
drift current is flow due to applied voltage across P-N junction & Diffusion is flow due to different concentration of hole & electron across P-N junction.
warning: [i read this definition somewhere, hence not my own work]
1:-- the definitions would means that diffusion current always exists between PN junction (say a diode) even when there is no applied voltage (means not connected to a power supply). but drift needs a power supply to exist.
2:-- while PN junction is having drift current, would there still exist diffusion current?
lead me to correct way please.
cheers
