ATL Electricity from Fruits Lab Kit – Compare Lemon, Potato, Tomato & Banana Batteries and Light an LED

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Ever wondered if a lemon can power a light? In this ATL lab kit, students turn everyday fruits into working batteries, measure voltage with a digital multimeter, compare the output of different fruits, and connect multiple cells in series to light an LED. It’s a hands-on way to understand electrochemistry, voltage, and simple circuits.

What You'll Build

By the end of this experiment, you’ll have a multi-cell fruit battery that lights an LED, along with a data table comparing the voltages of lemon, potato, tomato, and banana cells. You’ll see how series connections increase total voltage — just like commercial batteries — and learn to troubleshoot a real circuit.

What You'll Learn

• How to measure DC voltage with a digital multimeter
• The role of zinc and copper electrodes in creating a galvanic cell
• Why different fruits produce different voltages (pH and electrolyte content)
• How to wire cells in series to achieve a target voltage
