What must happen to the electric current in power lines before it can safely enter your home

Answer

step down

Explanation

High voltages are very risky when using them. They can destroy electric devises if not controlled. High voltages are only required in factoring and industries.

The voltages in the power lines are very high. For safety purposes, this voltages are stepped down before they are distributed to the end users.

This reduces the risks when the consumers are using electricity.

We use the step down transformers to reduce these voltages in the power lines before they are supplied to the users.

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.
