FAQs:

Q1: What is the fundamental law in electiricity?

A1: Ohms law – At constant temperature, the current flowing through a conductor is directly proportional to the potential difference(p.d) in volts across the two ends of the given conductor and inversely proportional to the resistance (R) in ohms (Ω) between the ends of the same conductor. V =IR

Solved example:

1. An electrical iron carrying 2A at 120V. Find resistance of the device?

Soln : R = (v/i) = 120/2 = 60 ohm

Q2: Explain Kirchoff’s current and voltage law.

A2: : Kirchoff’s current law – KCL states that the total current entering a junction is equal to the total current leaving the junction. (or)

The algebraic sum of the currents at the junction (node) will be zero.

At node n, (2 + 3 + 4) = (1 + 6 + 5)

Or 2 + 3 + 4 − 1 − 6 − 5 = 0.

Kirchoff’s voltage law – KVL is based on the law of the law of conservation of

the energy, states that the algebraic sum of voltage drops in a closed loop is zero.

1 + 2 + 3 =

1 + 2 + 3 – = 0

{Flow of currents in loop is assumed +ve from higher potential to lower potential in elements and +ve from lower to higher potential in Sources}

Q3: What are the basic electrical quantities?

A3: Three basic electrical quantities are,

- Current – The concept of electricity arises through observation of nature. A force between objects is observed, that, like gravity, acts at a distance. Charge is the name given to this source of force.
**Current**is the flow of charge.Current is reported as the number of charges per unit time passing through a boundary. - Voltage -Voltage between two points mathematically expressed as the change of energy experienced by a charge
- Power –
**Power**is defined as the rate energy is transformed or transferred over time. Power is measures in units of joules/second which is also known as*watts*.
