Microbes such as bacteria have small positive charges when in solution. Public health agencies are exploring a new way to measure the presence of microbes in drinking water by using electric forces to concentrate the microbes. Water is sent between the two oppositely charged electrodes of a parallelplate capacitor. Microbes in the water collect on one of the electrodes.a. On which electrode will the microbes collect?b. How could the microbes be easily removed from the electrodes for analysis?

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
