The product of voltage times amperage is known as what?

Select one:
a. Amperes
b. Current
c. Resistance
d. Power

The pressure proportional to the area a- inversely b- directly c- increase d-decrease

What organization and environment is described above?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
