Explanation:
1. First, let's find the total resistance of the circuit. We begin by combining , and :
Now time to combine and and they are connected in series so
Note that and are connected in parallel so
Finally, is connected in series with so the total resistance is
2. The total current in the circuit is
3. The voltage drop across is
4. We can see that . To solve for , we need , which is just , which gives us
5. From #2 & #4, and we also know that the voltage drop across is 7 V, the same as that of . The voltage drop across is
This means that the voltage drop across is 7 V - 5.4 V = 1.6 V. Knowing this, the current through is
Answer:
a scientist examines the results and answers the lab question- last choice
