Start with sodium for target material. Keep the voltage of the battery at 0. Change light intensity and/or light wavelength;a. Draw your observations (use arrows to represent the relative velocity of electrons)b. Record the magnitude of the electric current

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

cant without the picture! ?

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
