determine el valor de la potencia electrica que experimente un circuito el cual se somete a 120 voltios emitidos por accion de las cargas electricas que viajan a través de el y que experimentan 4 amperios de intensidad, durante todo el trayecto del mismo.

Responder: 480 vatios

Explicación:

La potencia en un circuito eléctrico am puede expresarse como el producto si la corriente y el voltaje en el circuito.

Potencia = corriente × voltaje

Corriente dada = 4 amperios

Voltaje = 120 voltios

Potencia gastada en el circuito = 4 × 120

Potencia gastada en el circuito =

480 vatios

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
