1

Resistance is opposition to which of the following?

70% Answer Correctly

conductance

voltage

current

impedance


Solution

Resistance is opposition to the flow of current and is measured in ohms (Ω). One ohm is defined as the amount of resistance that will allow one ampere of current to flow if one volt of voltage is applied. As resistance increases, current decreases as resistance and current are inversely proportional.


2 How would you connect 8 [12V 5A] batteries to achieve a combined power output of 96V 5A?
53% Answer Correctly
orthogonal
perpendicular
series
parallel

Solution

Connecting the 8 batteries in series multiplies their voltage while keeping their current the same yielding a 96V 5A configuration. Connecting the 8 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 12V 40A configuration. Using a series-parallel connection, 4 batteries can be connected in series and 4 can be connected in parallel resulting in a 48V 20A configuration.


3

Capacitors connected in series produce __________ capacitance compared to capacitors connected in parallel.

46% Answer Correctly

no

less

more

the same


Solution

Capacitors store electricity 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 connected in series produce less capacitance than capacitors connected in parallel.


4

The sum of the voltage drops across each resistor in a __________ circuit will equal the total voltage applied to the circuit.

54% Answer Correctly

series

series-parallel

parallel

closed


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.


5

A capacitor to an electronic circuit is like a _______________ to a house?

66% Answer Correctly

storage shed

safe

driveway

gate


Solution

Capacitors store electricity 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.
