Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Liang is working with an electrical circuit. She replaces a straight electrical wire with a coiled wire.What is Liang most likely trying to do?
A
increase the strength of the magnetic field when current flows through the circuit
B
decrease the strength of the magnetic field when current flows through the circuit
C
increase the current that flows through the wire when the circuit is active
D
decrease the current that flows through the wire when the circuit is active
Explanation: 

Detailed explanation-1: -How would this change affect the electric circuit? A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine. Badri makes the table below to review the factors that affect the electric force between objects.

Detailed explanation-2: -Current is inversely proportional to the resistance. A threefold increase in the resistance would cause a threefold decrease in the current.

Detailed explanation-3: -Electric Current is the flow of electrons through a wire or solution.

Detailed explanation-4: -Resistors are electronic components that resist the flow of electricity in a circuit. Resistors are used in electric circuits to adjust current and voltage, in much the same way as faucets are used to adjust the flow of tap water.
