Final answer:
Fixed resistors have a constant ohmic value, which does not change under specified conditions, making the statement (A) True. Ohm's Law relates voltage drop across a resistor to the current through it multiplied by its resistance.
Step-by-step explanation:
Fixed resistors are components with a defined resistance that does not change with applied voltage or current, environment temperature, aging or frequency of the operating conditions. This contrasts with variable resistors, like potentiometers or rheostats, which allow you to change their resistance value. In the context of electronics and physics, a true fixed resistor has a constant ohmic value under specified conditions, making the statement in question (A) True.
Per Ohm's Law, the voltage drop across a resistor in a circuit is calculated by multiplying the current through the resistor by its resistance (V = IR). In a series circuit, the current through each resistor is the same, while in a parallel circuit, the voltage drop is the same across each resistor. However, it is false to assume that the voltage is the same at every point in a wire in a circuit, as voltage drops occur across resistors or other components in the circuit.
