Equation for efficiency
Efficiency = useful output-total input
Efficiency = useful output/total
input
Efficiency=total input/useful output
Efficiency = useful output -total
input
What is the unit for energy?
Hertz
Joule
Watt
Coulomb
There are units for efficiency
FALSE
TRUE
What are the 3 fossil fuels?
Coal natural gas and minerals
Coal oil and natural gas
Coal oil and wood
What is meant by thermal conductivity?
Rate at which a material melts
Rate at which a material conducts electricity
The rate at which a material conducts heat
Rate at which a material cools down
The work done equation is?
Work done = energy transferred x distance
Work done = force x distance x time.
Work done = force x distance.
Work done = time x distance.
What is the unit for power
Inch
Pascal
Watt
Joule
(a) is the rate of flow of charge.

What does the fuse do?
Decrease volt
The fuse protects the person using it from electric shocks.
The fuse protects the appliance from
overheating if too much current flows.
Make it look pretty.
What does the EARTH wire do.
Protects the appliance from overheating if too much current flows
Increases voltage
Protects the user from an electric shock in case the live wire touches the casing of an appliance.
Protects the user from an electric shock in case the neutral wire touches the casing of an appliance.
What is the equation that links
current, power and potential
difference?
Power = potential difference /
current (P=VI)
Power = potential difference x
current (P=VI)
Power = current squared x resistance
(P=I2R)
What is the equation that links
current, resistance and power?
Power = current squared x resistance
(P=IsquaredR)
Power = potential difference /
current (P=VI)
Power = potential difference x
current (P=VI)
What is the unit for charge
Volts
Pascals
Coulombs
Amps

closely packed, vibrate
around fixed positions.
far apart, particles move
randomly at varying speeds.
close together, can flow
over each other.
Name the state change solid to gas
