If you wanted to increase the voltage, which would you use?
a. generator
b. step-up transformer
c. step-down transformer
d. motor
e. detector

The correct answer of the question is :  B) Step-up transformer.

EXPLANATION :

Before coming into any conclusion, first we have to understand the step-up and step-down transformer.

The step-up transformer is the transformer whose transformer ratio is greater than one. It means it will increase the voltage of the source or decrease its current.

On the other hand, the transformer ratio of step-down transformer is less than one. Hence, it will decrease the higher voltage to lower voltage or increase the lower current into higher current of the given source.

As per the question, we want to increase the voltage of the source.

Hence, we have to use step-up transformer.

it would be kevlar ^^

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
