Science Research Paper: “Potato Battery” I. Problem a. Main Problem This study aims to prove whether fruits and vegetables are good reserves of electricity. The potato‚ known for its high Phosphoric Acid and Sulfuric Acid‚ has been as our chosen fruit to prove and conduct our answers upon the accessibility of fruits and vegetables as an effective renewable energy source. b. Sub-Problems To further provide extra and specific information‚ the researchers have decided to add the following

GASEOUS DISCHARGE LAMPS: A gaseous discharge lamp is essentially a glass or quartz envelop containing two electrodes and a small quantity of gas or vapour at a low pressure. In these lamps light is obtained by applying an electric potential difference to a gas or vapour contained by the lamp under a suitable pressure. Due to application of electric potential difference gas gets ionised and an electric current flows; the tube is filled with a luminous discharge. The light spectrum

needs of their life cycle. Plants are most affected by blue light and red light. The color of light is a major consideration when you grow plants indoors. Fluorescent light that contains lots of blue light is good for starting seeds indoors. Full spectrum fluorescent light will encourage growth and flowering. The light produced by a metal halide lamp is intense blue‚ which is good for growing plants. Some greenhouses use high-sodium grow lights that yield abundant red light‚ to induce flowering and fruiting

Why Save Electricity? With the rising costs and shrinking economy more and more people are acting responsible and seacrhing for reasonable ways to save electricity. The other reason apart from these are that saving electricty will bring down your electicity bills‚ save you money and decrease pollution. Although many people have shifted to renewable sources such as solar power‚ there are other electricty saving tips too which will help you to conserve power. Electricity Saving At Home Replace

Want to be the most dazzling queen in the party? An engineer named Bertho Stoltiens shared his shiny earrings Blinkring designed‚ The earrings have a diameter of about 31mm eardrop‚ the total number of 12 LED were set in a circle above. This concept of the earrings is based on standard Cr2032 button-type battery with a slightly larger circular printed circuit board (PCB)‚ the operation of the LED parts required is a small circle on the board outside the battery. Stoltiens came across a number

We have probably all – at one time or another – been succored into to buying an appliance or electrical device based off whether it’s the cheapest one. By doing this you have been fooled by society! Your purchase should not be based on price‚ but by how much energy the appliance consumes. The appliance might be cheaper‚ but it mostly

A SMALL STEP TOWARDS CONSERVING ELECTRICITY In response to the task given to me‚ regarding fans and lights being left unshut when not in use and a small survey to analyse student mentality and behaviour‚ I had taken the following steps Informed people in my hostel to gather in the common room for 5 minutes after dinner (on Sunday‚ 24-08-2104).

Ways to save electricity Nowadays many people have electricity‚ but they don’t know how to use it wisely. There is many way to save electricity. We must use electricity wisely. 1. Way is only use electricity when needed. 2. Replace all of your inefficient incandescent light bulbs with energy efficient CFL bulbs. Replace halogen spotlights with much more efficient and longer lasting LED Spotlight. 3. Hang your clothes out to dry rather than using an electric tumble dryer. Ideally use a spin dryer before

module. Likewise‚ the tail lamp is replaced with a 10mm red LED. The battery pack is a combination of five 1.2V‚ 600mAh Ni-Cd cells‚ connected in series to produce an output of 6V DC. When you ride the bicycle‚ the dynamo touching the wheel spins around and diodes D1‚ D2‚ D3 and D4 form a bridge via which buffer capacitor C1 charges. When the dynamo voltage is sufficiently high‚ the low-current 5V relay energises and the DC supply available across C1 is routed to the head lamp (LED1) driver circuit
