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

A. Resistor
B. parallel circuit
C. Closed circuit*****
D. Series circuit

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. Series circuit is being changed into a parallel circuit

Use ohms 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

In a closed circuit the current only flow from the power source to an electrical device such as a lamp

A true*****
B. false

1. Reed

#1 is wrong.

2. BUBBLES

Thank you. I say the answer is B

3. Reed

No, #1 is still wrong.

I think you are wrong on #2. I don't know #3. #4 is correct.

4. duck

he never gave a answer reed that's why he came here

5. That Girl

1.D-Series circuit
2.A-An open circuit is being changed into a closed circuit
3.A-insulators
4.C-3.0ohms
5.B-False

6. Cool chick

100% that girl is right! I'm from CCA and just took it! Good job that girl

That Girls right thanks! Also I go to KCA and if you have the telephone bell shaped enclosures its a insulator that's the answer.
