Chapter 11: Problem 12

In u curtain UJT, \(r_{\mathrm{H}}^{\prime}=2.5 \mathrm{kS}\) and \(r_{\mathrm{kz}}^{\prime}=4 \mathrm{k \Omega}\). What is the intrinsic standoff ratio?

Short Answer

Expert verified
The intrinsic standoff ratio (\(\eta\)) for this UJT can be calculated using the formula \(\eta = \frac{r_H鈥瞹{r_H鈥� + r_{kz}鈥瞹\). Given \(r_H' = 2.5 k\Omega\) and \(r_{kz}' = 4 k\Omega\), we can plug in the values and find \(\eta = \frac{2.5 k\Omega}{6.5 k\Omega} = \frac{5}{13}\).

Step by step solution

01

Identify Given Values

We are given: - \(r_H' = 2.5 k\Omega\) - \(r_{kz}' = 4 k\Omega\)
02

Calculate Intrinsic Standoff Ratio

We can find the intrinsic standoff ratio (\(\eta\)) using the formula: \(\eta = \frac{r_H鈥瞹{r_H鈥� + r_{kz}鈥瞹\) Now, plug in the given values: \(\eta = \frac{2.5 k\Omega}{2.5 k\Omega + 4 k\Omega}\)
03

Solve for Intrinsic Standoff Ratio

Solve the equation to get the intrinsic standoff ratio: \(\eta = \frac{2.5 k\Omega}{6.5 k\Omega} = \frac{5}{13}\) The intrinsic standoff ratio is \(\frac{5}{13}\).
