Voltage must decrease by a factor of 3 to reduce the current in the resistor by a factor of 3
Answer: Option A
<u>Explanation:</u>
According to ohms law, the voltage passed in a circuit will be directly proportional to the current flow in the circuit. So the resistance of the resistor will act as proportionality constant in ohms law. Let us consider V as original voltage producing a current I in resistor of resistance R. Then according to ohms law:
Now the revised current flow in the circuit is reduced by a factor of 3, So the new current is in the same resistance R, then the new voltage will be
So, the voltage must be reduced by a factor of 3 to reduce the current in the resistor by a factor of 3.
Answer:
B object at rest
Explanation:
object at rest means it wouldn't be moving, like a parked car or sleeping person therefore, B is the correct answer
Both move with constant speed
