What Makes An Electric Force Stronger? The strength of the electric force between any two charged objects depends on the amount of charge that each object contains and on the distance between the two charges. As the amount of charge gets bigger, the force gets bigger, and as the distance between the two charges gets
Why Is Electric Potential Important? The electric potential is another useful field. It provides an alternative to the electric field in electrostatics… The potential energy for a positive charge increases when it moves against an electric field and decreases when it moves with the electric field; the opposite is true for a negative charge. What
What Is The Two Difference Between AC And DC Current? In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. How do you tell the difference between AC and DC? The difference between AC and DC lies in the
What Is The Direction Of Electric Field Line? These pattern of lines, sometimes referred to as electric field lines, point in the direction that a positive test charge would accelerate if placed upon the line. As such, the lines are directed away from positively charged source charges and toward negatively charged source charges. What is
Which Of The Following Best Describes An Electric Voltage? Answer: It is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V). What best describes a
Which Current Is Better AC Or DC? Alternating current is cheaper to generate and has fewer energy losses than direct current when transmitting electricity over long distances. Although for very long distances (more than 1000 km), direct current can often be better. Is DC current Better than AC? DC power is significantly more energy efficient
Which Subatomic Particle Has No Charge? There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don’t have a charge. What is a zero charged particle? Neutrons are a type of subatomic
Why Do Combs Attract Hair? When a comb is run through your hair charges pass between your hair and the comb, so the comb becomes charged either positively or negatively, and the hair oppositely charged. When the comb is brought close to paper an opposite charge is induced in the paper, and the opposite charges
Is Human Skin Positively Charged? The direction of charge flow depends on the relative positions of the materials in the triboelectric Is the human hand positively or negatively charged? An electroscope initially has a net negative charge. The foils come together when the electroscope is touched by a human hand because a. humans have a
What Are The Properties Of An Electric Charge? Charge is a scalar quantity. Charge is transferrable, they transfer from one body to another. Like charges repel each other and unlike charges attract each other. Charge is always associated with mass. Which of the following properties is not shown by charge? A: Charge cannot exist without
