what is ohmic and non-ohmic resistors?
Hi,
OHMIC RESISTORS are those which follow Ohm's law i.e. V=IR at constant temperate. They have a linear graph between Voltage (V) and Current (I). Example: Copper wire. NON-OHMIC RESISTORS are those which don't at all obey Ohm's law. Their V-I graph is non-linear. Example: PN Junction diode, Transistors etc.
@Shradha, Right answer. Keep writing! Thumbs up from the team of experts!
