Question
Answer
What is a positively charged particle in an atom found in the nucleus called?
A proton
What is a particle with no charge in an atom found in the nucleus called?
A neutron
What is a negatively charged particle that orbits the nucleus in an atom called?
An electron
True or False? : An atom has the same amount of positive charges as negative charges?
True
What is a thing which allows electricity and heat to pass through it easily called?
A conductor
What is a thing which reduces the amount of electricity pass through (sometimes may not allow it to pass at all) and a poor thermal conductor called?
An insulator
What is the rate of flow of charge called?
Current
Yes or No: Is current used up in a circuit?
No
What is a flow of electrons from one place to another called?
An electric current
What is a complete and closed path wherein electric current can flow through called?
A circuit
True or False?: It's more difficult for the electrons to flow through thin wires in the bulb as some of their energy is transferred into heat and light energy?
True
Yes or No: Are electrons pushed through the positive terminal of a cell?
No
Which adjective describes current which flows from the positive side of the cell to the negative side?
Conventional
What is the movement of eletrons through a wire from the negative side of a cell to the positive side of a cell called?
An electron flow
What is a route which is easier for the current to flow through than the circuit route called
A short circuit
What is a circuit which components are placed in one continuous loop called?
Series circuit
Yes or No: If there is a break in the circuit, can the current still flow?
No
True or False: The more bulbs there are; the dimmer each bulb will be?
True
What is a circuit wherein the current divides into two or more paths before recombining to make a full circuit called?
Parallel circuit
Yes or No: If one bulb breaks in a parallel circuit but the others are still working, is there still are complete circuit?
Yes
Yes or No: If you add more bulbs in a parallel circuit, will it affect the brightness of each bulb?
No
What is it called when the electrical components will try to prevent the electrons pass through them?
Resistance
Does copper have a low resistance or a high resistance?
Low
Which letter is the symbol for Resistance?
R
Question
Answer
What is resistance measured in?
Ohms
Formula for Resistance: R = ? / C ; Resistance = ? / Curent. What is the '?'

An ammeter
Is an ammeter connected in series or in parallel?
In series
What is current measured in?
Amperes / Amps
Which letter is the symbol for Current?
I
True or False: If you put an ammeter in different positions in a series circuit, they will all be the same?
True
True or False: If you put an ammeter in different positions in a parallel circuit, they will all be the same?
False
What is a measure of the difference in energy between two parts of a circuit called?
Potential difference
What is another word for potential difference?
Voltage
What is potential difference measured in?
Volts
Which letter is the symbol for volts?
V
Is a voltmeter connected in series or in parallel?
In parallel
True or False: In a series circuit, the potential difference splits between the components?
True
True or False: In a parallel circuit, the voltage is the same in each branch?
True
What is a component which allows current to flow only in one direction called?
A diode
What does an LED stand for?
Light Emitting Diode
Which is more efficient: LED or Bulb
LED
An LED changes electrical energy to what?
Light energy
What does an LDR stand for?
Light Dependent Resistor
Is an LDR a conductor or semiconductor
Semiconductor
