AC stands for alternating current which means that the current flows in both directions. So instead of flowing from one source to another, the current can flow from both the source and the recipient to each other. AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current
On the other hand DC voltage stands for direct current. This means that the current only flows in one direction. DC can be obtained from: solar cells, batteries etc. in this type of circuit the electrons move from the negative to positive poles. Compared to the AC voltage, DC is much weaker.

These actually work faster than fuses do. RCCBs jobs are to detect if there is a difference between neutral and live wires. This device disconnects itself when it senses a difference between the two. This is because the electric current is not balanced as it should be. Once it disconnects itself, it will be much safer as there will be a less chance for electrocution. These types of circuits are widely used where there is a need for fire protection such as lighting circuits. Also, nowadays these are being used a lot to help detect leakages in …show more content…
One of the main organs that electricity can really harm is the heart. The heart can become ‘frozen’ or fibrillated. If the heart is frozen there is a greater chance for it to return to normal beating rather than if it was fibrillated. In the case of fibrillation the heart’s muscles can all move at once and be all over the place. The heart won’t be able to function as normal. Current approaches 100milliamps or more can be fatal. The skin will result in numerous burns from the electricity and there could also be damages cells. In order to prevent such things from happening anyone that is going to be working on electricity should wear plastic gloves as plastic repels
