1

This circuit diagram represents a(n):

69% Answer Correctly

parallel circuit

series circuit

series-parallel circuit

open circuit


Solution

A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.


2

The formula specifying Ohm's law is which of the following?

77% Answer Correctly

\(V = {I \over R}\)

V = I2R

V = IR

\(V = {R \over I}\)


Solution

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.


3

Capacitors are charged by what type of current?

65% Answer Correctly

alternating

low voltage

high voltage

direct


Solution

Capacitors store voltage and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.


4

An engineer who wants to document an electric circuit would create which of the following?

67% Answer Correctly

a layout

a schematic

a matrix

a blueprint


Solution

A schematic is the proper name for a drawing of an electric or electronic circuit.


5 How would you connect 8 [6V 25A] batteries to achieve a combined power output of 6V 200A?
51% Answer Correctly
parallel
series
orthogonal
series-parallel

Solution

Connecting the 8 batteries in series multiplies their voltage while keeping their current the same yielding a 48V 25A configuration. Connecting the 8 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 6V 200A configuration. Using a series-parallel connection, 4 batteries can be connected in series and 4 can be connected in parallel resulting in a 24V 100A configuration.
