Asap! willing to give brainliest. 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 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. 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 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. 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.
