Chapter 22.1, Problem 8PP

To determine

To draw: An electrical series circuit with given specifications.

Answer to Problem 8PP

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

Explanation of Solution

Given:

Voltage of the battery, $V=60\text{V}$

Resistance of resistor, $R=12.5\Omega$

Formula used:

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

  $V=IR$

Calculation:

Series Circuit:

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

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

The series circuit for the given 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 current is,

  $I=\frac{V}{R}=\frac{60}{12.5}=4.8\text{A}$

So, the ammeter will read $I=4.8\text{A}$
