Chapter 22, Problem 48A

a.

To determine

To Draw:A simple circuit consisting of a resistor, a battery, and connecting wire.

Explanation of Solution

Introduction:

Current flows from the positive terminal of the batter to the negative end through the resistor or the load.

The schematic of a simple circuit is as follows

  

b.

To determine

The way, an ammeter must be connected in a circuit.

Explanation of Solution

Introduction:

An ammeter measures the current in a circuit.

To measure the current in a circuit, the ammeter must be connected in series to the load or resistor.

  

c.

To determine

The way,an voltmeter must be connected to a resistor to measure the potential difference across it.

Explanation of Solution

Introduction:

A voltmeter measures the potential difference across two points.

To determine the potential difference across a resistor, the voltmeter should be connected in parallel to the resistor.
