When reverse bias is enhanced the electric field at the junction also enhances. At some stage the electric field becomes so high that it breaks the covalent bonds building electron, hole pairs. Therefore a big number of carriers are created. This causes a large current to flow. This mechanism is known as Zener breakdown.
A sample of argon of mass 10.4 g occupies 2100 ml at 30 o C . (i) Calculate the work done by the gas when it expands isothermally against a constant external pressure of 3
At 200.0 K, germanium has 1.16 x 10 10 thermally liberated charge carriers/cm 3 . If it is doped with 1 As atom to 525,000 Ge atoms, what is the ratio of doped carriers to the
A jogger runs at a constant rate of 10.0 m every 2.0 s. The jogger starts at the origin, and runs in the positive direction for 3600.0 s.The figure below is a position-time graph s
The potential difference across a 4 ohm resistor is 20 volts. Suppose that all of the energy dissipated by this resistor is in the form of heat, how many joules of heat are ra
Simple Harmonic Motion II In physics, simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement. It can serve a
Mass as a Measure of the Amount of Inertia: All objects resist alters in their state of motion because they have inertia. However some objects have more of a tendency to resist
