What is Ohm's Law?

• Ohm's Law is a theory that explains the behavior of magnetic fields in conductors

• Ohm's Law states that the resistance in a circuit is inversely proportional to the current

• Ohm's Law is the relationship between resistance, current, and voltage in an electrical circuit

• Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

What are the three components of Ohm's Law?

• Mass, Acceleration, Force

• Speed, Distance, Time

• Voltage, Current, Resistance

• Temperature, Pressure, Volume

State Kirchhoff's Current Law.

• The total current entering a junction is equal to the total current leaving the junction.

• The total current entering a junction is less than the total current leaving the junction.

• The total current entering a junction is greater than the total current leaving the junction.

• The total current entering a junction is unrelated to the total current leaving the junction.

State Kirchhoff's Voltage Law.

• The sum of the voltage drops in a closed loop is unrelated to the applied voltage in that loop.

• The sum of the voltage drops in a closed loop is equal to the applied voltage in that loop.

• The sum of the voltage drops in a closed loop is greater than the applied voltage in that loop.

• The sum of the voltage drops in a closed loop is less than the applied voltage in that loop.

What happens to the total resistance in a series circuit?

• Remains the same

• Becomes negative

• Increases

• Decreases

What happens to the total resistance in a parallel circuit?

• decreases

• becomes negative

• stays the same

• increases

How is the total resistance calculated in a series circuit?

• By finding the average of the individual resistances

• By dividing the individual resistances

• By multiplying the individual resistances

• By adding up the individual resistances

How is the total resistance calculated in a parallel circuit?

• Using the formula Rt = R1 - R2 - R3 - ...

• Using the formula 1/Rt = 1/R1 + 1/R2 + 1/R3 + ...

• Using the formula Rt = R1 * R2 * R3 * ...

• Using the formula Rt = R1 + R2 + R3 + ...

What is a voltage divider?

• A device that increases the input voltage

• A circuit that produces an output voltage equal to its input voltage

• A type of battery used to store electrical energy

• A passive linear circuit that produces an output voltage that is a fraction of its input voltage.

Benjamin, Michael, and Ava are working on a project where they need to calculate the output voltage in a voltage divider circuit. How should they calculate it?

• Vout = Vin + (R2 / (R1 + R2))

• Vout = Vin * (R2 / (R1 + R2))

• Vout = Vin * (R1 / (R1 + R2))

• Vout = Vin / (R1 + R2)
