Two electronics students are discussing static electricity and electric current. Student A says that a basic
property of static electricity is the fact that it can’t be detected. Student B says that an electric current results when electrons move in a conductor. Which of the following statements is correct?
A. Only Student A is correct. C. Both of the students are correct.
B. Only Student B is correct. D. Neither of the two students is correct.
B. Only student B is correct.
To determine which statement is correct, let's examine the statements made by both Student A and Student B.
Student A states that a basic property of static electricity is the fact that it can't be detected. This statement is incorrect. Static electricity refers to an accumulation of electric charges on an object's surface, resulting in an imbalance of positive and negative charges. While it may not always be visible, static electricity can be detected through various means, such as by observing sparks, feeling shocks when touching an object, or using specialized equipment.
Student B states that an electric current results when electrons move in a conductor. This statement is correct. Electric current is the flow of electric charge in a conductor, and it is typically carried by moving electrons. When there is a potential difference (voltage) across a conductor, electrons are pushed or pulled by the electric field, causing them to move and establish a current.
Based on the analysis, the correct answer is B. Only Student B is correct.
