Question

ohmic resistance is . (a) junction diode (b) led (c) transistor (d) copper wire ​

Answer 1

The correct answer is option d) copper wire

The materials or components that obey the Ohm's law are said to be "ohmic" , which means that they produce the same value of resistance (R= V/I) regardless of the value of Voltage or current.

For ohmic components the graph of voltage versus current is a straight line.

From the above options only copper wire is an ohmic resistance.

Answer 2

Ohmic resistence is copper wire.

Explanation:

• A material's opposition to the flow of electric current; measured in ohms. electric resistance, electrical resistance, impedance, resistivity, resistance.
• Ohmic resistence  obey ohms law.
• Ohmic devices would be a wire, incandescent light bulb, electric stove heating element or a resistor.
• Materials that obey Ohm's law are described as ohmi which means they produce the same value for resistance.
• Example: all metallic conductors such as silver, aluminium, copper, iron etc.
