1 How would you connect 6 [6V 5A] batteries to achieve a combined power output of 6V 30A?
52% Answer Correctly
series
parallel
series-parallel
orthogonal

Solution

Connecting the 6 batteries in series multiplies their voltage while keeping their current the same yielding a 36V 5A configuration. Connecting the 6 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 6V 30A configuration. Using a series-parallel connection, 3 batteries can be connected in series and 3 can be connected in parallel resulting in a 18V 15A configuration.


2

This circuit component symbol represents a(n):

71% Answer Correctly

transistor

inductor

diode

capacitor


Solution

A diode allows current to pass easily in one direction and blocks current in the other direction. Diodes are commonly used for rectification which is the conversion of alternating current (AC) into direct current (DC). Because a diode only allows current flow in one direction, it will pass either the upper or lower half of AC waves (half-wave rectification) creating pulsating DC. Multiple diodes can be connected together to utilize both halves of the AC signal in full-wave rectification.


3

Inductance is a factor in which of the following?

44% Answer Correctly

batteries connected in serial

an AC circuit

a DC circuit

determining energy stored by a capacitor


Solution

Inductance is a property of an AC circuit (or a component in an AC circuit) that quantifies resistance to changes in current. The current in an AC circuit is continuously changing and inductive reactance (the opposition to change) depends both on the inductance of the circuit or component and the rate at which the current is changing.


4

The volt is a unit of measurement for:

79% Answer Correctly

current

power

capacitance

voltage


Solution

Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.


5

Which of the following is a characteristic of batteries connected in series?

61% Answer Correctly

two connections are made between each adjacent battery

the positive terminal of one battery is connected to the positive terminal of the next

total voltage equals the sum of the individual battery voltages

total voltage equals the average of the individual battery voltages


Solution

You can multiply the voltage or the current supplied by individual batteries by connecting them together either in series or in parallel. The characteristics of batteries connected in series are that total voltage equals the sum of the individual battery voltages, total current equals the average of the individual battery currents, the positive terminal of one battery is connected to the negative terminal of the next, and one connection is made between each adjacent battery.
