Answer:
- <u><em>B. The voltage is the same across all resistors in the circuit.</em></u>
<u><em></em></u>
Explanation:
The answer choices are:
- A.The current is the same across all resistors in the circuit.
- B.The voltage is the same across all resistors in the circuit.
- C. As more resistors are added, the current will decrease.
- D. The sum of the voltage drops will equal the total voltage.
<h2>Solution</h2>
In a simple <em>parallel circuit</em>, each component (resistor) is connected directly to the battery forming different branches or pathways to the current.
Thus, the ends of each resistor receives the total potential difference or <em>voltage</em> from the battery, which is what the <em>statement B</em>. asserts. Hence, <em>statement B is true</em>.
On the other hand, the current will split among the different pathways, following Ohm's law: the greater the resistance of the resistor the lower the current. Thus, the <em>statement A is false</em>.
For a parallel circuit, the total resistance decreases as more resistors are added, which means that, again following Ohm's law, the current will increase, contradicting the statement C. Thus, the <em>statement C is false. </em>
It is in the series circuit that 'the sum of the voltage drops will equal the total voltage"; in a parallel circuit the voltage drop is the just one and the same for each resistor. Thus, the <em>statement D is false,</em>too.
