Static electricity refers to the accumulation of electric charge on an object.
Explain the concept of charge
Charge is a fundamental property of matter, and it exists in two forms: positive and negative.
Differentiate between electrons and protons in terms of charge
Electrons carry a negative charge, while protons carry a positive charge
Describe what happens in terms of charge when objects are rubbed.
When objects are rubbed, electrons can be transferred from one object to another.
Explain the principles of attraction and repulsion in static electricity.
Like charges repel each other, and unlike charges attract.
Differentiate between static electricity and current electricity.
Static electricity involves the accumulation of charge at rest, while current electricity involves the flow of charge in a circuit.
Define and provide examples of an insulator.
An insulator does not easily allow the flow of electric charge.(glass, plastic, rubber, wood(?), ect )
Define and provide examples of a conductor.
A conductor is a material that allows the flow of electric charge. (Copper, Brass, Silver, Gold,Aluminium, ect.)
Define electricity
Electricity is the flow of electric charge
Complete the statement: "The path electricity takes is known as a ____________."
The path electricity takes is known as a circuit.
Explain the differences between series and parallel circuits.
Series circuit: Components are arranged in a single path. Parallel circuit: Components are arranged in multiple paths.
Explain the differences between series and parallel circuits.
Series Circuit:
In a series circuit, the components are connected in a single path, one after another.
The current flowing through each component is the same.
The total resistance in a series circuit is the sum of the individual resistances.
The voltage across each component adds up to the total voltage of the circuit.
Parallel Circuit:
In a parallel circuit, the components are connected in multiple paths, side by side.
The voltage across each component is the same.
The total resistance in a parallel circuit is less than the smallest individual resistance.
The current flowing through each component adds up to the total current of the circuit.
Explain what voltage (V) measures and name the instrument that measures it.
Voltage (V) measures the electric potential difference between two points in a circuit. It represents the amount of energy carried by each unit of electric charge. The instrument used to measure voltage is called a voltmeter.
List the units for voltage.
The units for voltage are volts (V).
Explain the use of a voltmeter and describe how it must be connected in a circuit.
A voltmeter is used to measure the potential difference (voltage) across a component or a circuit. It must be connected in parallel to the component or the section of the circuit where the voltage is to be measured.
Define and explain what current (I) measures.
Current (I) is a physical quantity that measures the flow of electric charge in a circuit. It is defined as the rate at which charge passes through a given point in a conductor.
List the units for current.
The units for current is Ampere (A)
Explain the use of an ammeter and describe how it must be connected in a circuit
An ammeter measures electric current in a circuit. It must be connected in series with the component being measured or parallel from the component being measured.
Explain the differences between current and voltage measurements in a series and parallel circuit.
In a series circuit, the current remains the same throughout the circuit, while the voltage is divided among the components. In a parallel circuit, the voltage remains the same across each component, while the current is divided among the branches.
State the principle that the current should measure the same wherever measured in a series circuit.
The principle that the current should measure the same wherever measured in a series circuit is known as the principle of conservation of charge.
State the principle that the sum of the voltages across each light should equal the voltage of the battery in a series circuit.
The principle that the sum of the voltages across each light should equal the voltage of the battery in a series circuit is known as Kirchhoff's Voltage Law (KVL).
State the principle that the sum of all current should equal the total current from the battery in a parallel circuit.
Kirchhoff's Current Law (KCL) states that in a parallel circuit, the sum of all currents should equal the total current from the battery.
List the units for resistance.
The unit for resistance is Ohm (Ω)
State the principle that the voltage will be the same across each component in a parallel circuit.
In a parallel circuit, the principle of voltage states that the voltage across each component remains the same.
Define the term AC/DC
when current flows in one direction it’s known as direct current(DC) .
When current is pulled forwards and backwards depending on the required amount of electricity it’s known as alternating current(AC)
Define resistance (R)
Resistance (R) is a measure of how much a material or component opposes the flow of electric current.
