Answer:
Question: CONDUCT THE EXPERIMENT using the Circuit Construction Simulator:
0.15 A
0.30 A CORRECT
0.45 A
0.60 A
Answer:
Question: Is this circuit arranged in series, in parallel, or in both formations?
Series CORRECT
Correct! Because there is only one path the electrons can take through this circuit, it is connected in series.
Parallel
Both series and parallel
Answer:
Question: Based on your answer from the previous question, use one of the following equations to calculate the total resistance of the circuit.
Resistance in Series:
Rtotal=R1+R2
Resistance in Parallel:
1Rtotal=1R1+1R2
6.67 Ohms
10 Ohms
20 Ohms
30 Ohms
CORRECT
Answer:
Question: Now, using Ohm’s Law:
I=VR
and the total resistance calculated in the previous question, what is the total current of this circuit?
0.15 A
0.30 A CORRECT
0.45 A
0.60 A
