ELECTRICAL UNITS Match up correctly: CURRENT (C) Joules Ω VOLTAGE (V) Ohms A RESISTANCE (R) Coulombs J POWER (P) Volts or Joules/coulomb W CHARGE (????) Amps or Coulombs/second V ENERGY (E) Watts or Joules/second C Once you have done this – write down as many symbol equations as you can remember for this unit

ELECTRICAL UNITS Match up correctly: CURRENT (C) Joules Ω VOLTAGE (V) Ohms A RESISTANCE (R) Coulombs J POWER (P) Volts or Joules/coulomb W CHARGE (????) Amps or Coulombs/second V ENERGY (E) Watts or Joules/second C Once you have done this – write down as many symbol equations as you can remember for this unit

3
**The Equations Q = C x t V = C x R E = V x Q E = P x t P = V X C V**

Where do they all come from?

4
**Electricity Revise the concept of charge and current**

Revise the concept of voltage and energy Revise the concept of Parallel and Series Circuits Back to the equations

5
Q = C x t Q C x t Charge = Current x Time Back to the equations

6
**V = C x R Voltage = Current x Resistance Remember VCR V C x R**

Back to the equations

7
**E = V x Q Energy = Voltage (pd) x Charge**

One Volt = One Joule given to One Coulomb of Charge Back to the equations

8
**E = P x t Energy = Power x Time**

The Power is the rate at which energy is transferred A Kettle uses 2300 Watts of power. If it is switched on for 5 minutes how much energy does it use? Back to the equations

9
**P = V x C Q C x t Power = Voltage x Current**

Increasing Voltage or Current means the rate of energy transfer increases A Kettle uses 2300 Watts of power. If it is switched on for 5 minutes how much energy does it use? The Kettle runs of mains electricity, What current does the kettle draw? Back to the equations

10
**Parallel and Series Circuits**

Remember ! Current Voltage series circuit same everywhere split up between components parallel splits up between branches same across each branch
