What is potential difference?
The work done in moving one
coulomb
of charge
View source
What is current?
A flow of
electrons
View source
What is charge?
The rate of flow of
electrons
View source
What is resistance?
The opposing of a
current
View source
What is power?
Energy
transferred in a certain amount of
time
View source
What does 'series' mean in a circuit?
All
components
follow directly from each other
View source
What does 'parallel' mean in a circuit?
The
current
has alternate
pathways
View source
What are free (or delocalised) electrons?
Electrons free to move through the
conductor
View source
What is the equation for charge?
Q
=
It
View source
What is the equation for potential difference?
V
=
IR
View source
How do you calculate total resistance in a series circuit?
Total resistance =
R1
+
R2
View source
What is the equation for power?
P
=
VI
View source
What is another equation for power?
P
=
I
x I x
R
View source
What is the equation for energy transferred?
E
=
Pt
View source
What is another equation for energy transferred?
E
=
QV
View source
What is the unit for current?
Amps
(A)
View source
What is the unit for potential difference?
Volts (V)
View source
What is the unit for charge?
Coulombs
(C)
View source
What is the unit for resistance?
Ohms (Ω)
View source
What is the unit for power?
Watts (W)
View source
What is the unit for energy transferred?
Joules
(J)
View source
How do electric fields behave between like charges?
Field lines
move from the electric field
View source
How do electric fields behave between unlike charges?
Field lines
move to the electric field
View source
What is static electricity?
A build-up of
charge
between two objects
View source
What happens if there is enough static electricity?
A
spark
will jump as a
discharge
View source
Do objects need to touch for a spark to occur?
No
,
they do not need to touch
View source
What is the National Grid?
A system of
overhead
or underground
cables
View source
Why does the National Grid use high voltage?
To make
energy
travel far easily
View source
How does high voltage affect the National Grid's efficiency?
It makes the National Grid more
efficient
View source
What are the key equations related to electricity?
Q = It (
charge
=
current
x time)
V = IR (
potential difference
= current x resistance)
Total
resistance
= R1 + R2
P = VI (
power
= potential difference x current)
P = I x I x R (power = current squared x resistance)
E = Pt (
energy transferred
= power x time)
E = QV (energy transferred = charge flow x potential difference)
View source
