Do electrical conductors have low mass density?
electrical conductors have low mass density. … electrical conductors have high tensile strength. c. electrical conductors have electric charges that move freely.
Which of the following materials is the best conductor of electricity?
Copper is the best conductor of electricity among given metals.
How would you define electric current?
Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point of the wire per unit of time. … In alternating current the motion of the electric charges is periodically reversed; in direct current it is not.
What is electric charge quizlet?
electric charge(define) a property that leads to electromagnetic interactions between the particles that make up matter. electric charge (describe) an object can have a positive, negative, or no charge.
Which statement best describes the relative conductivity of semiconductors?
Which statement best describes the relative conductivity of semiconductors? They are the most conductive elements.
Which of the following best describes the inner workings of conductors?
Which of the following best describes the inner workings of conductors? Electrons collide at random, experiencing a net change of position equal to zero, except when exposed to an external electric field.
Which of the following statement is correct about electric current?
Answer: (c) Electric current has both magnitude and direction but it does not follow the vector laws of addition. Therefore, it is scaler quantity.
What is the correct statement for an insulator?
An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials, semiconductors and conductors conduct electric current more easily.
Which statement describes the difference between an insulator and a conductor?
The difference between an insulator and a conductor is that an insulator is a material that does not allow charges to move easily while a conductor is a material that allows electrons to move around.
