Answer #1

in DC circuit, Ohm's law related voltage, current and resistance as,

V= IR

The voltage across the resistor is directily proportional to the current passing through the resistor.

(b)

the space around a electric charge or object within which a force would be exerted on other charged particles or objects is called electric field

(c)

magnet is a piece of iron or other material which has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field.

(d)

the space around a magnetic material or a moving electric charge within which the force of magnetism acts is called magentic field .
