One light bulb in a string of lights goes out. This causes all of the other lights in the string to also go out. This is an example of a

A. resistor.
B. parallel circuit.
C. closed circuit.
D. series circuit.


2.When a switch is turned from the off to the on position, it is changing the circuit in which of the following ways?

A. An open circuit is being changed into a closed circuit.
B. A closed circuit is being changed into an open circuit.
C. A parallel circuit is being changed into a series circuit.
D. A series circuit is being changed into a parallel circuit.


3.Early telephone poles had wires that connected inside bell-shaped glass enclosures like the ones shown below.

several bell-shaped glass enclosures

These glass enclosures helped to keep the electric current from moving outside the circuit of wires. The glass enclosures were used as

A. insulators.
B. conductors.
C. resistors.
D. switches.


4.Use Ohm’s Law to determine the resistance in a circuit if the voltage is 12.0 volts and the current is 4.0 amps.

A. 8.0 ohms
B. 48 ohms
C. 3.0 ohms
D. 12 ohms


5.In a closed circuit, the current only flows from the power source to an electrical device such as a lamp

A.TRUE
B.FALSE

    1.D yes
    2.A yes
    3.A yes
    4.im not sure please help V = i R
    12 = 4 R , R = 12/4 = 3 Ohms
    5.false. I agree but am not sure what it means. One could always have a short circuit where current streams through doing nothing useful.

    4 is C. and 5 is true.

  • science(check answers) -

    5 is false

  • science(check answers) -

    Actually Aaron, you need you need to re-read your lesson or something.
    1.d
    2.a
    3.a
    4 is not b it is c. Because Resistance=voltage/current.
    Resistance=12volts/4amps
    Resistance=3.0 ohms
    5.false
