Question

(1) Why was the transformer invented?

(2) Is electricity used in the human body?​

Answer 1

Explanation:

This transformer was created at the beginning of the modern electrical grid, the same year as the Frankfurt Electrical Exhibition which demonstrated long distance transmission of power. 1880s - today - Transformers are improved by increasing efficiency, reducing size, and increasing capacity.

Answer 2

Answer:

a) This transformer was created at the beginning of the modern electrical grid, the same year as the Frankfurt Electrical Exhibition which demonstrated long distance transmission of power. 1880s - today - Transformers are improved by increasing efficiency, reducing size, and increasing capacity.A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to "step up" or "step down" voltages and works on the magnetic induction principle.

b)Electricity is everywhere, even in the human body. Our cells are specialized to conduct electrical currents. Electricity is required for the nervous system to send signals throughout the body and to the brain, making it possible for us to move, think and feel.The average human, at rest, produces around 100 watts of power. [2] Over periods of a few minutes, humans can comfortably sustain 300-400 watts; and in the case of very short bursts of energy, such as sprinting, some humans can output over 2,000 watts
