A Zener diode is in reverse breakdown. The current through it doubles. The voltage across it
A diode breaks down at \(30\,\text{V}\). By which mechanism, and what happens to its breakdown voltage when it warms?
Zener breakdown happens in a junction that is
A regulator has \(V_{in} = 15\,\text{V}\), \(R_S = 200\,\Omega\), a \(9\,\text{V}\) Zener and a load of \(900\,\Omega\). The Zener current is
The longest wavelength a silicon photodiode (\(E_g = 1.1\,\text{eV}\)) can detect is about
An LED, a photodiode and a solar cell are used, in that order, with
A transistor with \(\beta = 100\) carries a base current of \(20\,\mu\text{A}\). Its emitter current is
\(Y = A \cdot B + C\) for the inputs \(A = 1\), \(B = 0\), \(C = 1\) is
A NAND gate with its two inputs joined together acts as
By De Morgan's theorem, \(\overline{A \cdot B}\) equals
