Chapter 22, Problem 66A

To determine

To draw: An electrical series circuit with given elements.

Answer to Problem 66A

An electrical series circuit with given elements is shown in Figure 1.

Explanation of Solution

Given:

The given values are:

Resistance of resistor, $R=16\Omega$

Ammeter reading, $I=1.75\text{A}$

Battery with voltage $V$

Formula used:

According to Ohm’s law, The voltage-current relationship is

  $V=IR$

Calculation:

Series Circuit:

A circuit in which one or more electrical elements are connected one by one in a chain making a single path is a series circuit.

The current through all the elements is same and the total voltage is distributed to all the elements.

The series circuit for the given element specification is,

  

Figure 1

The direction of conventional current is from positive to negative terminal outside the battery and negative to positive terminal inside the battery.

The value of voltage source is,

  $\begin{array}{c}V=IR\\ =1.75\times 16=28\text{V}\end{array}$
