1 How would you connect 10 [6V 5A] batteries to achieve a combined power output of 60V 5A?
53% Answer Correctly
orthogonal
series
series-parallel
parallel

Solution

Connecting the 10 batteries in series multiplies their voltage while keeping their current the same yielding a 60V 5A configuration. Connecting the 10 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 6V 50A configuration. Using a series-parallel connection, 5 batteries can be connected in series and 5 can be connected in parallel resulting in a 30V 25A configuration.


2 Use Ohm's Law to calculate the value of current in this circuit if voltage is 600 volts and resistance is 60 Ω.
81% Answer Correctly
10 A
5 A
20 A
15 A

Solution

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

Solved for current, I = \( \frac{V}{R} \) = \( \frac{600}{60} \) = 10 A


3 How would you connect 6 [15V 5A] batteries to achieve a combined power output of 15V 30A?
52% Answer Correctly
series
parallel
orthogonal
series-parallel

Solution

Connecting the 6 batteries in series multiplies their voltage while keeping their current the same yielding a 90V 5A configuration. Connecting the 6 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 15V 30A configuration. Using a series-parallel connection, 3 batteries can be connected in series and 3 can be connected in parallel resulting in a 45V 15A configuration.


4

Inductance is a factor in which of the following?

44% Answer Correctly

determining energy stored by a capacitor

a DC circuit

an AC circuit

batteries connected in serial


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.


5

Why does current in an electric circuit create heat?

77% Answer Correctly

current is naturally hot

voltage is naturally hot

heat is created when the current overcomes resistance in the wire

the wire in the circuit burns when current passes through


Solution

Current in an electric circuit creates heat when the current overcomes resistance in the wire.
