Define potential or voltage and provide its unit of measurement.
Define potential or voltage and provide its unit of measurement.
Potential or voltage is the capacity of a charged body to do work. The unit of potential or voltage is joule/coulomb or Volt (V), which can be expressed as $V = \rac{W}{Q}$.
Explain the concept of electric current and its unit of measurement.
Explain the concept of electric current and its unit of measurement.
Electric current is the flow of electron in a closed circuit. It is also defined as the amount of charge passing through the conductor in unit time. The unit of electric current is Ampere (A), which is equivalent to charge/second or $A = \rac{Q}{t}$.
Explain the concept of conventional current and electron current.
Explain the concept of conventional current and electron current.
Conventional current is the flow of positive charges, which is opposite to the actual flow of electrons. Electron current is the flow of actual negatively charged electrons in a circuit.
