Find the energy dissipated in 10 minutes in the diode in the circuit shown above.
The barrier potential across a diode is 0.7 V which remains constant. (Assume the diode to be ideal)
The PD across the diode is 0.7 V. The remaining voltage is (2.7 − 0.7 = 2 V) and the resistance offered to the current is 10 Ω. The current
I =\frac{V}{R}=\frac{2}{10}=0.2 AEnergy released in the diode = V × i × t
= 0.14 × 10 × 60 = 84 J
