Can you please help me with this exercise?
In each circuit, calculate the current flowing through the 10kΩ resistor and calculate the voltage drop across the germanium diode. Please assume that a germanium diode has a forward-biased junction potential of 0.3V.
Supply Voltage = 5V, R= 10kΩ, Junction potential = 0.3V, I =? VDrop=?
VD = (5V – 0.3V) = 4.7V
I = VD/R = 4.7V / 10kΩ = 0.47mA
Supply Voltage = 10V, R= 10kΩ, Junction potential = 0.3V, I =? VDrop =?
VD = (10V – 0.3V) = 9.7V
I = VD/R = 9.7V / 10kΩ = 0.97mA
Can you please review my solution?
I am not sure about the voltage drop, which in my calculation is indicated as VD. Also the second circuit, which is reverse biased, I'm not sure about the calculation I made.
Thanks in advance.
