Usually resistances used electronic circuitry

Usually resistances used in electronic circuitry use:

Right Answer is:

Ohmic and wattage ratings


Resistance is an element of a circuit or network which is inserted to lower the current in the circuit.

Usually, voltage V is constant 230 V (RMS) in household supply and wattage, P = V2/R

So, if we fix the value of R, Wattage(Power) will be fixed.

Or we can say if we know anyone between resistance(R) and wattage (P), others can be known.

Thus, the rating is ohmic and wattage for a resistor.
