Being a girl a generally spend some time getting ready for various events. Getting ready requires many different tools such as curling irons, flat irons, and hair dryers. These tools require a good amount of electricity to power and when you plug more then one of them into the plug the lights dim significantly. This is because the circuits that these are plugged into are only series circuits. This means there is only one path for the current to flow through and when you plug in another tool it requires a lot of extra electricity so the lights dim so enough energy can be pulled for the blow dryer. This way you the circuit wont blow out and a fire wont start even thought it is a possible.
