Examine the scenario.
A circuit is arranged so that 6 A of current is flowing through it.
If the voltage is then tripled, which option correctly describes the effect on the current?
a) When the voltage is tripled, there is a greater amount of energy to move 1 C of charge, but also a greater amount of resistance. So the amount of current will not be affected by a change in the voltage.
b) When the voltage is tripled, there is a greater amount of energy to move 1 C of charge, so the amount of current will triple as well. As the current increases, the voltage also increases.
c) When the voltage is tripled, there is no change in the amount of energy to move 1 C of charge. There is also no effect on the amount of current moving through the circuit. The amount of current moving through the circuit will stay the same.
d)When the voltage is tripled, there is a smaller amount of energy to move 1 C of charge. So that amount of current will reduce to 1/3 of the original current. As voltage increases, the current decreases.
B will "B" the answer! You get it? 😉
Yes.
Hahaha, Thank you @Anonymous! I really appreciate it!!
To determine the effect of tripling the voltage on the current, we need to consider the relationship between voltage, current, and resistance in a circuit. According to Ohm's Law, the current flowing through a circuit is directly proportional to the voltage across it and inversely proportional to the resistance. Mathematically, this can be expressed as:
Current (I) = Voltage (V) / Resistance (R)
In this scenario, the only change mentioned is tripling the voltage while the resistance is not specified. Let's analyze the options based on this information:
a) When the voltage is tripled, there is a greater amount of energy to move 1 C of charge, but also a greater amount of resistance. So the amount of current will not be affected by a change in the voltage.
This option suggests that increasing the voltage also increases the resistance, which is not specified in the scenario. Additionally, it claims that the current will not be affected by changing the voltage. This is not accurate and can be disregarded.
b) When the voltage is tripled, there is a greater amount of energy to move 1 C of charge, so the amount of current will triple as well. As the current increases, the voltage also increases.
This option correctly states that tripling the voltage will result in a corresponding increase in current. However, it incorrectly suggests that as the current increases, the voltage also increases, which is not the case. This option can be discounted.
c) When the voltage is tripled, there is no change in the amount of energy to move 1 C of charge. There is also no effect on the amount of current moving through the circuit. The amount of current moving through the circuit will stay the same.
This option states that tripling the voltage has no effect on the current. Since the relationship between current and voltage is defined by Ohm's Law, this option is incorrect.
d) When the voltage is tripled, there is a smaller amount of energy to move 1 C of charge. So that amount of current will reduce to 1/3 of the original current. As voltage increases, the current decreases.
This option correctly explains that increasing the voltage reduces the current in a circuit. As the voltage is tripled, the current will decrease to 1/3 of its original value. This is in accordance with Ohm's Law, which states that current is inversely proportional to voltage.
Therefore, the correct option is d) When the voltage is tripled, there is a smaller amount of energy to move 1 C of charge. So that amount of current will reduce to 1/3 of the original current. As voltage increases, the current decreases.
