Module 1 D.C. Circuits Electricity Quiz

The invisible energy that allows electrons to flow in a closed circuit and perform work.

A body gains a positive charge when some of its electrons are removed.

Electrons loosely attached to the nucleus of an atom that can move freely when energy is applied.

The practical unit of charge, representing the amount of charge carried by 6.24 x 10^18 electrons.

The ability of a charged body to perform work. It's a measure of how much energy is stored in the charged body.

The central part of an atom containing charged particles like electrons and protons.

The unit of electrical potential, representing the work done per unit charge.

The rate at which electric charge flows through a conductor.

The unit of electric current, representing one coulomb of charge flowing per second.

A fundamental law stating that the current flowing through a conductor is directly proportional to the potential difference applied across it.

Ohm's law does not apply to circuits containing non-linear elements like electric arcs, diodes, or transistors.

The force that drives electric current to flow, whereas potential difference is the energy one coulomb of charge uses to move between two points.

A body is said to have electrical potential if 1 Joule of work is required to charge the body with 1 coulomb.

Applying electrical potential across a metallic wire causes free electrons to drift towards the positive terminal of the cell.

The unit of electrical potential is volts, which represents Joules/Coulomb.

Ohm's law is not applicable to circuits containing diodes or transistors, as their resistance changes with the applied voltage.
