Basic Electricity 3, WASSCE (PC 2nd), 2019: Question and Answers
Aim
To investigate the effect of resistance on voltage in a direct current (d.c.) circuit.
Procedure
- Connect the circuit as shown in Fig. 1.
- Ask the supervisor to check the circuit connection.
- Use the resistance values provided in Table 1.
- Set the variable power supply to 6 V.
- Set the resistance box to 0 Ω.
- Close switch S.
- Read and record the ammeter and voltmeter readings in Table 2.
- Set the resistance box to 2 Ω and repeat the readings.
- Repeat the step for 4 Ω, 6 Ω, 8 Ω, and 10 Ω.
- Complete Table 2.
- Plot a graph of Power (W) on the vertical axis against Current Squared (I²) on the horizontal axis.
- Determine the slope of the graph.
Expected Table of Results
| Resistance (Ω) | Current (A) | Current Squared (I²) | Voltage (V) |
|---|---|---|---|
| 0.0 | 0.19 | 0.036 | 6.0 |
| 2.0 | 0.18 | 0.032 | 5.6 |
| 4.0 | 0.17 | 0.029 | 6.0 |
| 6.0 | 0.16 | 0.026 | 5.3 |
| 8.0 | 0.15 | 0.023 | 5.0 |
| 10.0 | 0.14 | 0.019 | 4.5 |
Observation
| Aspect | Chief Examiner’s Comment |
|---|---|
| Circuit Connection | Many candidates could not connect the circuit correctly. |
| Current Reading | Some candidates had difficulty taking accurate readings from the ammeter. |
| Voltage Reading | Errors were observed in recording voltmeter values. |
| Current Squared | Several candidates failed to compute I² correctly. |
| Graph Work | A number of candidates could not plot the required graph properly, leading to wrong slopes. Errors occurred in choosing scales, plotting points, and drawing the line of best fit. |
Atom and Its Forces
What is Electricity?
Electricity can be defined as the flow of electrons through materials and devices, or as the force that moves these electrons. Scientists explain that electricity is linked to very tiny particles called electrons and protons.
These particles cannot be seen with the naked eye, but they exist inside the atom as subatomic particles.
To clearly understand electricity, one must first understand the structure of the atom.
EO 1.1: Key Terms
Below are the basic terms used in describing electricity and atomic forces:
- Electrostatic Force: The force of attraction or repulsion between two charged particles.
- Electrostatic Field: The region around a charged particle in which other charges experience a force.
- Potential Difference: The work done in moving a unit charge between two points in an electric field.
- Electromotive Force (EMF): The energy supplied per unit charge by a source such as a battery or generator.
- Ion Charge: The positive or negative charge that an atom or molecule acquires when it gains or loses electrons.
The Atom
Atoms are the basic building blocks of all matter. It is the smallest particle of an element that retains the chemical properties of that element.
An atom consists of a positively charged nucleus surrounded by negatively charged electrons. This makes the atom electrically neutral overall.
The nucleus contains two types of subatomic particles:
- Proton: Carries a single positive charge (+).
- Neutron: Slightly heavier than the proton and carries no charge (neutral).
Electrons, which carry a fundamental negative charge (-), move around the nucleus in concentric orbits known as shells.
The arrangement of these particles depends on the element involved, giving each atom its unique properties.
The Proton and Electrostatic Force
The Proton and Atomic Number
The proton is the fundamental positive charge (+) in an atom, located at the center in the nucleus.
The number of protons in the nucleus of an atom determines the atomic number of that element.
For example, a carbon atom has six protons in its nucleus, making its atomic number six.
In a natural state, an atom contains an equal number of protons and electrons. Since the negative charge (-) of each electron
balances the positive charge (+) of each proton, the atom as a whole is said to be electrically neutral.
Electrostatic Force
One of the most fascinating aspects of the atom is the attraction between the nucleus and the electrons.
This attraction is known as electrostatic force. It is the force that keeps electrons in orbit around the nucleus.
Electrostatic force is often represented by lines showing how electrons are drawn toward the positively charged nucleus. Without this force, electrons would not remain in their paths, and the stability of atoms would be lost.
Electrostatic Force and the First Law of Electrostatics
The Role of Electrostatic Force
Without electrostatic force, electrons moving at very high speed would not remain in their orbits.
This attraction between the negatively charged electrons and the positively charged nucleus ensures the stability
of atoms. Objects or particles that attract or repel in this way are known as charged bodies.
The First Law of Electrostatics
The negative charge of an electron is equal in magnitude but opposite to the positive charge of a proton.
These opposite charges are known as electrostatic charges. In nature:
- Unlike charges (positive and negative) attract each other.
- Like charges (positive-positive or negative-negative) repel each other.
This principle is called the First Law of Electrostatics or the law of electrical charges,
and it is one of the most important concepts in electricity.
Charge Transfer Between Objects
Some atoms can lose electrons while others can gain them, making it possible for electrons to move from one object to another.
When this happens:
- The object with an excess of electrons becomes negatively charged.
- The object with fewer electrons becomes positively charged.
Objects containing billions of atoms will still follow the same electrostatic principles as individual protons and electrons. The electrons that are able to move freely are called free electrons. The more free electrons present in an object, the stronger its negative electric charge. In this way, electric charge can be seen as a measure of electrons.
Electrostatic Field
A charged particle or object creates an invisible force around it known as an electrostatic field.
This field is responsible for the attraction or repulsion between charged bodies.
The strength and direction of the field can be illustrated using lines of force.
