Question
What will be the power dissipation across a silicon diode carrying a current of 50mA?
Choose the best option:
- 25mW
- 50mW
- 35mW
- 100mW
Solution
To calculate the power dissipation across a silicon diode, we use the formula:
P = IV
where: P is the power dissipation, I is the current, and V is the voltage.
For a silicon diode, the voltage is typically about 0.7V.
Given that the current I is 50mA, or 0.05A, we can substitute these values into the formula:
P = 0.05A * 0.7V = 0.035W or 35mW
So, the power dissipation across a silicon diode carrying a current of 50mA is 35mW.
