study aims to find out how long a lemon (Citrus limon) can last as a lemon battery powering a digital clock. B. HYPOTHESIS The researcher assumes that one lemon would last for a day or two and that the usage of more lemons would entail a longer battery time. C. OBJECTIVES Specifically‚ it aims to: 1) come up with a quantity-longevity ratio with the use of a varied quantity of lemons in the production of a lemon battery 2) find the relationship of the number of lemons and the time it powers

Chemistry Batteries [Chemistry HSC Course-1] What is an Anode? An anode is the negatively charged electrode of an electrical device but in this a primary cell‚ that supplies current. What is a Cathode? A cathode is the positively charged electrode of an electrical device which in this case is a primary cell‚ that supplies current. What is Current? A flow of current which results from the ordered directional movement of electrically charged particles. A current is the rate of flow of charge

+ R2) 0.25A V=V (Ra + R1) 0.75A = (Ra + R2) 0.25A (Ra + R1) 3 = Ra + R2 3Ra + 3R1 = Ra + R2 2Ra = R2 – 3R1 Ra = 0.5(R2 – 3R1) 3. In a simple series circuit a battery is connected through an ammeter to an electric lamp. A voltmeter is connected parallel to the lamp. The ammeter reads 0.75 A and the voltmeter 50 V. What is the resistance of the lamp neglecting the current drawn by the voltmeter? If the current in the voltmeter is 0.001

CASE STUDY: POTENTIAL MARKET FOR MAINTENANCE FREE CAR BATTERIES In spring each year‚ a festival is held at the tomb of Shah Hussain in the city of Lahore. Devotees light earthen lamps at the start of the of festival. Lighting of lamps is a metaphor for killing the inner darkness in ourselves. On his first visit to Lahore (Pakistan)‚ Zhang Huan was impressed by the number of vehicles plying in the city. His main interest was to see Lahore in colour on the eve of “The festival of lamps”.

Electric Charge and Electric Field:-> 1. Electric Charge Electric charge is a fundamental property like mass‚ length etc associated with elementary particles for example electron‚ proton and many more. Electric charge is the property responsible for electric forces which acts between nucleus and electron to bind the atom together. Charges are of two kinds (i) negative charge (ii) positive charge Electrons are negatively charged particles and protons‚ of which nucleus is made of‚

Introduction and Experimental Goal: An electric field surrounds all electrically charged particles. With electric fields‚ one can determine the effects of all of the charges in the environment. In this lab entitled “Electric Fields and Potential Mapping”‚ the main goal obtained was to examine and deliberate the effects of an electric field and electric potential. Examples of some effects of electric fields include resultant forces‚ changes in motion‚ changes in current flow‚ etc. By using conductive
