Chapter 1, Problem 1RQ

One millivolt is one millionth of a volt.

(a) True (b) False

To determine

Find whether the given statement is true or false.

Answer to Problem 1RQ

The given statement is “(b) False”.

Explanation of Solution

Discussion:

The given statement is “One millivolt is one millionth of a volt”.

Refer to Table 1.2 in the textbook for SI prefixes. From the table, it is clear that one millivolt is equivalent to ${10}^{-3}\text{V}$. Therefore, write the expression as follows:

$\begin{array}{c}1\text{mV}={\text{10}}^{-3}\text{V}\\ =\frac{1}{1000}\text{V}\end{array}$

Therefore, one millivolt is equivalent to one thousandth of a volt. Hence, option (b) is correct.

Conclusion:

Thus, the given statement is “(b) False”.
