This is a picture of my friend Courtney and I taking pictures of ourselves as seen on tv!!! ok yea so its a camera hooked up to the Tv but its still pretty cool. The tv is connected to the power outlet in the wall with has a voltage of either 120 V or 0V at any moment. The current flows through the complete circuit starting from the 120 V outlet to the tv where the charge is used and the V is returned to zero until the new electrons from the outlet are supplied. Because the outlet is 120 the charge of the electrons will be 120. The tv also has some resistance so that the real charge used will not be the full 120. THe more resistant the circuit the smaller the current. YAY we are on tv :0
