Introduction

“Juice” is a slang term sometimes used for electricity. Batteries are made up of one or more cells. Cells often consist of two different materials in a solution that are connected to each other by a wire. In this experiment, you will study some basic principles of cells using the juice of a lemon as the cell solution.

Objectives

  • Build several cells.
  • Measure cell voltages.
  • Discover which combinations produce a voltage.
  • Decide which combination makes the “best” battery.
