How Does the Length of a Wire Affect Its Resistance?

Obviously it is not due to the current because both have the same electrical current flowing through them. When we look at the equation P= IV, P being the power output I being current Envy being voltage drop, the current through both bulbs must've been the same if they were wired in series, therefore the voltage drop must have been much higher for the glowing bulb, and it resulted in the larger power output on like the other bulb which probably had a lower power output. Homes law states that the voltage drop is equal to the current flowing through times resistance. The resistance of the battery had a direct effect on the power output because again the current stay the same throughout the circuit. Power is still giving off by both, but because one of the resistance is is higher and one of the bulbs it burns much brighter, Andrews results in more light being output.

the chemical energy stored in batteries gets transformed into electrical energy through the wires, then gets transformed into light energy and thermal energy that you see.

Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole. Devices inbetween convert this energy to another form, Efficieny- e.motor=85%, combustion= 20%

To understand how this electricity works we must start with the basics. The atom is the smallest unit of matter, consisting of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Electric charges that are the same repel each other and charges that are different attract each other. Electric charges can exist alone, unlike magnetic poles.

1. Why do electrons (blue dots) move? Draw a diagram of the battery, label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery.

A majority of Americans are constantly worried about bills. One of the bills people are most concerned about is the electricity bill. The electric bill varies each month based on the usage of different electrical uses and appliances. Also, have you ever wondered why when you turn off one light, the light in the other room stays on? Well I will explain the type of electric circuits that is used to ensure that. I will also explain the relationship between what you use and how the duration of use can have an impact the cost of the electric bill.

The electrons move because they experience a electric current force in the wire. The battery causes an electric field and the electrons experience a force due to that field. The current flows in the opposite direction of the electrons and the flow of the

Voltage represents electric potential energy per unit charge. If a unit of electrical charge was placed in a location, the voltage indicates the potential energy of it at that point. Basically, it is a measurement of the energy contained within an electric circuit or electric field at a given point.

In the article “energy story” it talks about all the importance of electrity and how it is made. It informs you about the different number of protons electrons and neutrons that are used to make electricity. We use electricity for everything in the

In the story “Energy Story”, it talks about what electricity is and how it can be created. It tells you about how protons, electrons, and neutrons interact with each other to make electricity. The story gives you examples of electricity that affects your everyday life, for example, electricity, lights up our homes, and cooks our food, etc.

Electric potential: When observing my electric bill, the concept of Electric potential is an interesting component regarding the electric bill. One of the fundamentals

Without getting too technical, electricity is the result of a chemical reaction. As a Berkeley teacher’s guide to this experiment demonstrates, the penny is copper, while the galvanized nail is coated in zinc. When zinc, which is negatively charged, comes into contact with an acid, electrons are freed in a chemical reaction. Copper, which is positively charged, accepts those electrons, thereby creating an electric circuit.

An electricity and magnetism phenomenon apparently unrelated to power are electrical magnetic fields. We are familiar with these forces through the interaction of compasses with the earth's magnetic field, or through fridge magnets or magnets on children's toys. Magnetic forces are explained in terms very similar to those used for electric forces:

Electrical components of equipment provide power. Electronic components of equipment provide power. Electronic components control the equipment, although many types of equipment still controlled with electrical devices.(Career Information Center) Electrical and electronic engineers may supervise crews of electrical workers who do routine work in the generating station. They often use their knowledge of electrical engineering technology to diagnose electrical workers to do them. Some electrical and electronic engineering technicians work for industrial plants that use electricity.(Career Information Center) Electrical engineers apply their knowledge of the science to working with equipment that produces and distributes electricity, such as generators, transmission lines, and transformers. They also design, develop, and manufacture electric motors, electrical machinery, and ignition systems for automobiles, aircraft, and other engines.(Careers In Focus: Engineering pg.55) Electrical engineers focus on high-power generation of electricity and how it is transmitted for use in lighting homes and powering factories. They are also concerned with how equipment is designed and maintained and how communications are transmitted via wire and airwaves. Engineers use basic knowledge collected by scientist to solve a
