DC Electric Circuits - Electric Current and Circuits

Question 1

electric current

Answer 1

• An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma.

Question 2

electric circuit

Answer 2

• 1) In electronics, a circuit is a path between two or more points along which an electrical current can be carried. (A circuit breaker is a device that interrupts the path when necessary to protect other devices attached to the circuit - for example, in case of a power surge.)

Question 3

conductors

Answer 3

• Conductors are materials that permit electrons to flow freely from particle to particle.

Question 4

insulators

Answer 4

• The behavior of an object that has been charged is dependent upon whether the object is made of a conductive or a nonconductive material.
