Question

How are closed circuits and open circuits different?

A) If the circuit is closed, there is no break in the circuit, and electric current will flow
B) If the circuit is closed, there is a break in the circuit, and electric current will flow
C) If the circuit is open, there is no break in the circuit, and electric current will flow
D) If the circuit is open, there is a break in the circuit, and electric current will flow

Answer 1

A) If the circuit is closed, there is no break in the circuit, and electric current will flow. D) If the circuit is open, there is a break in the circuit, and electric current will not flow. The key difference between open and closed circuits is the presence or absence of a complete path for electric current to flow. In a closed circuit, the path is complete, and electric current can flow. In an open circuit, the path is broken, and electric current cannot flow.
