Which of the following is a conducting loop in which electrons carrying electric energy may be transferred from a suitable source to do a useful work and returned to the source?
a.) Direct current
b.) Indirect current
c.) Electric circuit
d.) source of energy
That is called a circuit.
The correct answer is c.) Electric circuit.
To determine the correct answer, let's break down the options and understand their meanings:
a.) Direct current: Direct current refers to the flow of electric charge in a single direction. It is commonly used in devices like batteries and is not specifically related to conducting loops.
b.) Indirect current: There is no commonly known term as "indirect current" in the field of electricity. It seems like an incorrect or misleading term.
c.) Electric circuit: An electric circuit is a closed loop or pathway through which electric current flows. It consists of interconnected components such as wires, resistors, capacitors, and other electrical devices. In an electric circuit, a conducting loop is established to allow the flow of electrons carrying electric energy from a suitable source, such as a power supply, to perform useful work, like powering a lightbulb, motor, or any other electrical device. The electrons then return to the source in a continuous loop.
d.) Source of energy: A source of energy refers to any device or system that can provide electrical energy, such as generators, batteries, solar panels, etc. While a source of energy is essential for powering an electric circuit, it is not specifically the conducting loop in which electrons flow to do useful work.
Based on the explanations above, the correct answer is c.) Electric circuit, as it encompasses the concept of a conducting loop through which electrons can flow to transfer electric energy and do useful work before returning to the source.
