Q-3. write down the definition of current, voltage ,EMF , power and energy.
→ (i) Current :- Electric Current is the rate of flow of electrons in a conductor. The SI Unit of electric current is the Ampere. Electrons are minute particles that exist within the molecular structure of a substance.
(ii) Voltage :- Electric Current is the rate of flow of electrons in a conductor. The SI Unit of electric current is the Ampere. Electrons are minute particles that exist within the molecular structure of a substance.
(iii) EMF :- EMF is also known as electromotive force. The electric potential produced by either an electrochemical cell or by changing the magnetic field. The potential difference between two points is defined as the amount of work done in moving a unit charge from one point to another.
(iv) Power :- Electric power is the rate at which work is done or energy is transformed into an electrical circuit. Simply put, it is a measure of how much energy is used in a span of time.
(v) Energy :- The energy that has been converted from electric potential energy. We can define electrical energy as the energy generated by the movement of electrons from the point to another. The movement of charged particles along/through a medium constitute current or electricity.
Q-4. Explain the ohm's law, Kirchhoff’s voltage law and Kirchhoff’s current law.
→ (i) Ohm's Law :- Ohm’s law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm’s law is V=IR.
(ii) Kirchhoff’s voltage law :- Kirchhoff’s Voltage Law goes by several names as Kirchhoff’s Second Law and Kirchhoff’s Loop Rule. According to the loop rule, the sum of the voltages around the closed loop is equal to null. The total current entering a junction or a node is equal to the charge leaving the node as no charge is lost.
(iii) Kirchhoff’s current law :- Kirchhoff’s Current Law goes by several names as Kirchhoff’s First Law and Kirchhoff’s Junction Rule. According to the Junction rule, in a circuit, the total of the currents in a junction is equal to the sum of currents outside the junction.
Q-5. Difference between series and parallel connections / Circuit.
→ Series Connection :- A circuit is said to be connected in series when the same current flows through all the components in the circuit. In such circuits, the current has only one path. Let us consider the household decorative string lights as an example of a series circuit. This is nothing but a series of multiple tiny bulbs connected in series. If one bulb fuses, all the bulbs in series do not light up.
Parallel Connection :- A circuit is said to be parallel when the electric current has multiple paths to flow through. The components that are a part of the parallel circuits will have a constant voltage across all ends.
Q-6. Explain the AC circuits terms.
→ AC circuits as the name (Alternating Current) implies are simply circuits powered by an Alternating Source, either voltage or current. An Alternating Current or Voltage, is one in which the value of either the voltage or the current varies about a particular mean value and reverses direction periodically.
Q-7. Explain energy audits.
→ Power logger connection in order to do an energy audit An energy audit is an inspection survey and an analysis of energy flows for energy conservation in a building. It may include a process or system to reduce the amount of energy input into the system without negatively affecting the output.

Q-8. Explain the Basic construction and applications of DC motor?
→ The construction is same for DC motor and DC generator. The working principle and operation of a DC machine is based on an effect when a current carrying conductor coils laying in a magnetic field, the magnetic field produces a mechanical force on it known as torque which rotates the conductor coils in magnetic field.
Q-9. Explain the Basic construction and applications of DC generator.
→ Basic construction and working of a DC Generator. A dc generator is an electrical machine which converts mechanical energy into direct current electricity. This energy conversion is based on the principle of production of dynamically induced emf.
