ELECTRICITY AND CURCITS
An Understanding of Electrcity

Types of Electricity
Ohm's law works with the relationship between the voltage and the current in a conductor. The relationship shows that the difference between voltage and a conductor is proportional to the current through it.
V (Voltage), I (Current) R (Resistence)
There are three factors in ohm's law.
Ohm's Law is given by:
- V = I R
- Voltage = Current (x) Resistance
- The voltage, current and resistance all rely on each other. If one is changed the others will be affected. For example, if the voltage is increased the current will increase which may cause the conductor to explode if there is no resistance. This is because the electrons are moving too fast. If the resistance is increased the electrons will move at a slower rate.
