Your answer: —  Â·  Correct: B
Explanation

A capacitor is a passive electronic component designed specifically to store electric charge and energy in the form of an electrostatic field [t1][t3]. It consists of two conductive plates separated by an insulating material called a dielectric [t1][t6]. When connected to a voltage source, opposite charges (+Q and -Q) accumulate on these plates, creating a potential difference [t1][t2]. In contrast, an inductor stores energy in a magnetic field when current flows through it [t4], while a resistor dissipates electrical energy as heat rather than storing it [c1][t5]. Transformers are used to transfer electrical energy between circuits via electromagnetic induction and do not store charge [t4]. Therefore, the capacitor is the device characterized by its capacity to hold an electric charge, a property measured in Farads [t3][t6].
