There is a light bulb on the left and a battery with three components on the right. The top of the battery is labeled “Cathode” and has a positive charge. The middle of the battery is labeled “Electrolyte” and has a negative charge. The bottom of the battery is labeled “Anode” and has a negative charge. The line between each section is labeled with a negative sign as well. There is a line coming out of the bottom of the battery that turns to the left and is labeled with a negative sign. The line makes a 45 degree turn to the top, goes through the light bulb, continues up and then turns to the right and then another turn into the top (cathode) of the battery.
