Electric Circuit 1 (Recall)

The "influence" that makes current flow from lower to higher potential is called __________.

• Electromagnetic Force

• Electromotive Force

• Electronegative Force

• Electromagnetic Induction

The motion of charge from one region to another is called ________. It is also the rate at which charges flow.

• Current

• Resistance

• Voltage

• Potential

What is this electrical element?

• Current

• Resistor

• Capacitor

• Transducer

Which of the following is true about resistance?

• It is directly proportional to the area of the conductor

• It is inversely proportional to the length of the conductor

• The higher the temperature the lower the resistance

• The smaller the area of the conductor the greater is its resistance

Which of the following correctly describes the circuit shown?

• The bulbs are connected in parallel

• The bulbs are connected in series

• The bulbs are connected in series and parallel combination

• The bulbs is neither connected in series nor parallel

What would happen if more and more electrical elements are connected in series?

• The resistance increases therefore current will increase

• The resistance increases therefore current will decrease

• The resistance decrease therefore current will increase

• The resistance decrease therefore current will decrease

Three identical light bulbs are connected in series to a battery. When one light bulb is removed, what will happen to the remaining light bulbs?

• The remaining two light bulbs will glow brighter with the same brightness

• The remaining two light bulbs will becomes dimmer

• The remaining two light bulbs will not glow

• The remaining two light bulbs will glow with different brightness

Complete the following statement: A simple series circuit contains a resistance R and an ideal battery. If a second resistor is connected in parallel with R,

• the voltage across R will decrease

• the current through R will decrease

• the total current through the battery will increase

• the equivalent resistance of the circuit will increase

Jason’s circuit has a 24-Ω resistor that is connected in series to two 12-Ω resistors that are

connected in parallel. JoAnna’s circuit has three identical resistors wired in parallel. If the

equivalent resistance of Jason’s circuit is the same as that of JoAnna’s circuit, determine the

value of JoAnna’s resistors.

What is the equivalent resistance?

• Cannot be determined
