A student says: 'Static electricity and current electricity are the same because both involve charge.' Which response is the most accurate?
AThe statement is correct because all electricity is identical in behavior
BThe statement is incorrect because static electricity deals with charge at rest, whereas current electricity deals with charge in motion
CThe statement is incorrect because current electricity has no charge involved
DThe statement is correct only for metallic conductors
Answer & Solution
Correct answer: B. The statement is incorrect because static electricity deals with charge at rest, whereas current electricity deals with charge in motion
The underlying distinction is the state of the charge. Static electricity studies charge at rest, while current electricity studies charge in motion. So although both involve electric charge, they are not the same branch in this classification. Option C is wrong because current is precisely due to moving charge, and D adds an irrelevant restriction.
