Shocking!
Last year, i was blow-drying my little sister's hair and when i put the blow-dryer into the outlet, i got shocked. When i inserted the plug into the outlet, i accidentally put my finger too close to where the circuit was completed. I then realized that i completed a circuit when i plugged in the hair dryer. I did a little more research. I found out that the voltage of an outlet in a home is 120 Volts. Then i did research to find out the resistance in the blow-dryer. The blow-dryer i used had a resistance of 6 ohms. Using the equation I= (V/R) (I being the current, V being the voltage, and R being the resistance in Ohms), i found out that i was shocked with 20 amps of current. I went further to calculate that the Power generated in that circuit, from the equation P=(I*V) was 2400 W of power.
Curcuits can be simple or complicated and they can generate a lot of current and power. I am glad that i wasn't hurt because if the voltage was greater and the resistance was smaller, i could have been in quite the predicament.
