Calculating Forward Bias Resistance of a Diode
To calculate the forward bias resistance of a diode, we can use the formula R = ΔV / ΔI, where R is the forward bias resistance, ΔV is the change in voltage across the diode, and ΔI is the change in current through the diode.
Given Data
- Initial forward bias voltage (V1) = 0.6 V
- Final forward bias voltage (V2) = 0.7 V
- Initial current (I1) = 5 mA = 0.005 A
- Final current (I2) = 15 mA = 0.015 A
Calculating Change in Voltage and Current
- ΔV = V2 - V1 = 0.7 V - 0.6 V = 0.1 V
- ΔI = I2 - I1 = 0.015 A - 0.005 A = 0.01 A
Calculating Forward Bias Resistance
- R = ΔV / ΔI = 0.1 V / 0.01 A = 10 Ω
Therefore, the value of the forward bias resistance of the diode is 10 Ω.
