Dc Theory Level 2 Lesson 4

Question: When two batteries are connected as a series additive power source, they produce a voltage that is less than either of the batteries connected by itself.

Answer: False

Question: When voltage sources are connected in series, the total voltage is equal to the algebraic sum of the individual voltages.

Answer: True

Question: When two batteries are connected as series additive power sources, the positive terminal of one battery is connected to the positive terminal of the other battery.

Answer: False

Question: The power sources in the circuit are connected in a ? configuration.

Answer: Series-Opposing

Question: What is the formula for the total voltage applied to a series circuit when using two series-opposing power sources?

Answer: E total= E larger - E smaller

Question: In a series circuit, the total or sum of all the voltages dropped across all of the circuit components is equal to the source voltage.

Answer: True

Question: As current increases in a series circuit, the voltage dropped across each load in that circuit will ? .

Answer: Increase

Question: What is the formula which defines the voltage drop across loads in a series circuit?

Answer: E=IxR

Question: In a circuit with two resistors in series, the voltage dropped across the resistor with the larger resistance value will be less than the voltage dropped across the resistor with less resistance.

Answer: False

Question: In a series circuit, loads which have the same voltage dropped across them will have ? .

Answer: The same resistance values
