What is happening if energy input remains constant and voltage remains the same in a circuit, but the current decreases?
A. The resistance has increased.
B. The volts have decreased.
C. The power has increased.

Respuesta :

A. The resistance has increased. Because here current is decreasing. Option C is incorrect cuz Power will decrease as resistance decreases according to equation P= v^2/R. V = volts, R = resistance. Hope it helps

I believe the correct answer from the choices listed above is option A. If energy input remains constant and voltage remains the same in a circuit, but the current decreases, then the resistance has increased. This relationship states that: The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.

V = IR

So, I and R are inversely proportional. 

Hope this answers the question.
