Question 1

The total resistance of a parallel circuit is equal to the reciprocal of the sum of the reciprocals of the individual resistances.

Accepted Answer

In a parallel circuit, the total resistance (R_total) is indeed calculated by taking the reciprocal of the sum of the reciprocals of the individual resistances (R1, R2, R3, etc.), expressed as 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Question 2

A circuit must contain a minimum of three different elements: a power source, a complete path for current flow, and a load.

Accepted Answer

A basic electrical circuit requires a power source to provide voltage, a conductive path for current to flow, and a load to consume the electrical energy.

Question 3

In a series circuit, which resistor will dissipate the most wattage?&#10;A) the one with the smallest resistance&#10;B) the one with the largest resistance&#10;C) the second largest resistance&#10;D) they will all be the same

Accepted Answer

In a series circuit, the current is the same through all components. Power dissipation (wattage) in a resistor is given by P = I^2R, where P is power, I is current, and R is resistance. Therefore, the resistor with the largest resistance will dissipate the most power since the current squared is multiplied by the resistance value.

Question 4

In a series circuit, the current is the same value throughout the entire circuit.

Accepted Answer

In a series circuit, the same current flows through all components because there is only one path for the current to take.

Question 5

To find the total resistance in a series circuit, you would ____ the individual resistances.&#10;A) add&#10;B) subtract&#10;C) multiply&#10;D) take the reciprocal of the sum of

Accepted Answer

In a series circuit, the total resistance is found by simply adding up the individual resistances of all components in the series.

Question 6

In a circuit with light bulbs connected in parallel, if one light bulb burns out, all of the light bulbs will fail to light.

Accepted Answer

In a parallel circuit, each light bulb operates independently, so if one bulb burns out, the others will continue to light up.

Question 7

To calculate the current flowing in a series circuit, divide the ____ by the ____.&#10;A) resistance; voltage&#10;B) power; resistance&#10;C) resistance; power&#10;D) voltage; resistance

Accepted Answer

The current in a series circuit is calculated by dividing the voltage by the resistance, according to Ohm's Law (I = V/R).

Question 8

In a combination circuit, the ____ of all individual wattages will equal the total circuit wattage.&#10;A) sum&#10;B) difference&#10;C) product&#10;D) ratio

Accepted Answer

In a combination circuit, the total circuit wattage is determined by adding up the wattages of all individual components, hence the correct answer is the sum of all individual wattages.

Question 9

How many paths for current flow are in a parallel circuit?&#10;A) zero&#10;B) one only&#10;C) one or two&#10;D) two or more

Accepted Answer

In a parallel circuit, there are two or more paths for current to flow, allowing electricity to pass through multiple components simultaneously.

Question 10

In a parallel circuit, the ____ across the individual branch circuits will be the same.&#10;A) resistance&#10;B) current&#10;C) voltage&#10;D) power

Accepted Answer

In a parallel circuit, the voltage across each branch is the same, regardless of the individual resistances or currents in those branches.
