The current flowing in a certain p-n junction at room temperature is 2...
The current in a p-n junction is given by the diode equation:
I = I_s * (e^(V_d / V_t) - 1)
where I is the current, I_s is the reverse saturation current, V_d is the voltage across the diode, and V_t is the thermal voltage.
In this case, a large reverse bias voltage is being applied, which means V_d is negative. Let's assume V_d = -100 V.
At room temperature, the thermal voltage is approximately 25 mV (V_t = 0.025 V).
We can rearrange the diode equation to solve for I_s:
I = I_s * (e^(-100 / 0.025) - 1)
Solving for I_s:
I_s = I / (e^(-100 / 0.025) - 1)
= 2 x 10^-7 A / (e^(-100 / 0.025) - 1)
Using a calculator, we find:
I_s ≈ 1.84 x 10^-19 A
Therefore, the current flowing in the p-n junction at room temperature is approximately 1.84 x 10^-19 A.
I = I_s * (e^(V_d / V_t) - 1)
where I is the current, I_s is the reverse saturation current, V_d is the voltage across the diode, and V_t is the thermal voltage.
In this case, a large reverse bias voltage is being applied, which means V_d is negative. Let's assume V_d = -100 V.
At room temperature, the thermal voltage is approximately 25 mV (V_t = 0.025 V).
We can rearrange the diode equation to solve for I_s:
I = I_s * (e^(-100 / 0.025) - 1)
Solving for I_s:
I_s = I / (e^(-100 / 0.025) - 1)
= 2 x 10^-7 A / (e^(-100 / 0.025) - 1)
Using a calculator, we find:
I_s ≈ 1.84 x 10^-19 A
Therefore, the current flowing in the p-n junction at room temperature is approximately 1.84 x 10^-19 A.
