Eeny, meeny, miny, moe, the answer you're looking for is c: it's equal to the sum of the voltage drops across each component! And by the way, I'm impressed you're electric-minded. Let me know if you need any more shocking answers!
The correct answer is c. The total voltage provided by the battery in a series circuit is equal to the sum of the voltage drops across each component.
To determine the correct answer, we can recall the properties and behavior of a series circuit. In a series circuit, components such as resistors, capacitors, and other devices are arranged sequentially, with the same current passing through each component.
Now, let's examine each option:
a. The total voltage provided by the battery is equal to the voltage across each component: This statement is not correct. In a series circuit, the sum of the voltage drops across each component equals the total voltage provided by the battery, but the voltage across each component is not necessarily equal to the total voltage.
b. The total voltage provided by the battery is greater if the resistance is increased: This statement is not correct. In a series circuit, increasing the resistance will not change the total voltage provided by the battery. The total voltage remains constant regardless of changes in resistance.
c. The total voltage provided by the battery is equal to the sum of the voltage drops across each component: This statement is correct. In a series circuit, the total voltage provided by the battery is equal to the sum of the voltage drops across each component. This is known as Kirchhoff's voltage law.
d. The total voltage increases as the time the battery is connected increases: This statement is not correct. The total voltage provided by the battery does not depend on the amount of time it is connected in a series circuit. The total voltage remains constant as long as the battery is connected.
Therefore, the correct answer is c. The total voltage provided by the battery is equal to the sum of the voltage drops across each component.
