a) How are voltage, current and resistance of a circuit related?
b) What is an electric field?
c) What is a magnet?
d) What is a magnetic field?
please type your responses.
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 .
