While working on her science fair project venus connected a battery to a circuit that contained a light bulb. venus decided to change the light bulb to a higher resistance, but she keeps the current the same. what will happen to the voltage? a) it will increase. b) it will decrease. c) it will fluctuate. d) it will remain the same.

The correct answer is

A)It will increase

In fact, the relationship between the voltage, the resistance and the current in a circuit is given by Ohm's law:

where

V is the voltage

I is the current

R is the resistance

From the equation, we see that the voltage is directly proportional to the resistance; therefore, if the current I is kept the same and the resistance R is increased, the voltage V will increase too.

the total distance traveled by the car is

30km + 49km = 79 km .
