What is a positively charged particle in an atom found in the nucleus called?
What is a particle with no charge in an atom found in the nucleus called?
What is a negatively charged particle that orbits the nucleus in an atom called?
True or False? : An atom has the same amount of positive charges as negative charges?
What is a thing which allows electricity and heat to pass through it easily called?
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?
What is the rate of flow of charge called?
Yes or No: Is current used up in a circuit?
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?
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?
Yes or No: Are electrons pushed through the positive terminal of a cell?
Which adjective describes current which flows from the positive side of the cell to the negative side?
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?
Yes or No: If there is a break in the circuit, can the current still flow?
True or False: The more bulbs there are; the dimmer each bulb will be?
What is a circuit wherein the current divides into two or more paths before recombining to make a full circuit called?
Yes or No: If one bulb breaks in a parallel circuit but the others are still working, is there still are complete circuit?
Yes or No: If you add more bulbs in a parallel circuit, will it affect the brightness of each bulb?
What is it called when the electrical components will try to prevent the electrons pass through them?
Does copper have a low resistance or a high resistance?
Which letter is the symbol for Resistance?
What is resistance measured in?
Formula for Resistance: R = ? / C ; Resistance = ? / Curent. What is the '?'
Which instrument measures current
Is an ammeter connected in series or in parallel?
What is current measured in?
Amperes / Amps
Which letter is the symbol for Current?
True or False: If you put an ammeter in different positions in a series circuit, they will all be the same?
True or False: If you put an ammeter in different positions in a parallel circuit, they will all be the same?
What is a measure of the difference in energy between two parts of a circuit called?
What is another word for potential difference?
What is potential difference measured in?
Which letter is the symbol for volts?
Is a voltmeter connected in series or in parallel?
True or False: In a series circuit, the potential difference splits between the components?
True or False: In a parallel circuit, the voltage is the same in each branch?
What is a component which allows current to flow only in one direction called?
What does an LED stand for?
Light Emitting Diode
Which is more efficient: LED or Bulb
An LED changes electrical energy to what?
What does an LDR stand for?
Light Dependent Resistor
Is an LDR a conductor or semiconductor
When light falls on a LDR, will more electrons pass or less electrons
Which device is able to control the size of current by altering the resistance by moving a slider which controls the length of a wire?
A variable resistor / a rheostat
