Science (Grade 8)
1. What will happen to the current if the voltage is decreased by one half while the resistance is held constant?State the relationship of voltage and current base on your answer.
2. What will happen to the current if resistance is doubled while voltage is kept constant? State the relationship of current and resistance based on your answer.
i really need help on this one...

Answer:
1.The current is directly proportional to the voltage and inversely proportional to the resistance. Any alteration in the voltage will result in the same alteration of the current.
2.The current is directly proportional to the voltage and inversely proportional to the resistance. Any alteration in the voltage will result in the same alteration of the current. So doubling or tripling the voltage will cause the current to be doubled or tripled. On the other hand, any alteration in the resistance will result in the opposite or inverse alteration of the current. So doubling or tripling the resistance will cause the current to be one-half or one-third the original value.
