Chapter 2, Problem 2.1P

To determine

The value of voltage through the resistor.

Answer to Problem 2.1P

The voltage across the resistor is $72.6\text{V}$ .

Explanation of Solution

Given Information:

Current $i=2.2\text{mA}$

Resistance $R=33\text{kΩ}$

Calculation:

Ohm’s law: It states that voltage between two points of conductor is directly proportional to current flowing through it.

  $v\propto i$

  $v=iR$

Here, $R$ is constant resistance.

Substitute $2.2\text{mA}$ for $i$ and $33\text{KΩ}$ for $R$ in the above equation.

  $\begin{array}{c}v=2.2\text{mA}\times 33\text{kΩ}\\ =\text{2}\text{.2}\times {\text{10}}^{-3}\times 33\times {10}^3\\ =72.6\text{V}\end{array}$

Conclusion:

Hence, the voltage across the resistor is $72.6\text{V}$ .
