Q3. What is oms law What resistance unit
Ans. 
Ohm's Law is a fundamental principle in electrical engineering that relates the current flowing through a conductor to the voltage across it and the resistance of the conductor.
• Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across it and inversely proportional to the resistance (R) of the conductor.

• The formula for Ohm's Law is: V = I * R, where V is the vol...read more

Q1. What is current?
Ans. 
Current is the flow of electric charge through a conductor.
• Current is measured in Amperes (A).

• It is the rate of flow of electric charge.

• Current flows from high potential to low potential.

• There are two types of current - AC (Alternating Current) and DC (Direct Current).

• Examples of current sources include batteries, generators, and power plants.

Q2. Define Resistance?
Ans. 
Resistance is the opposition to the flow of electric current in a circuit.
• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in a conductor.

• Higher resistance leads to lower current flow in a circuit.

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.

• Examples of resistors include light bulbs, heating elements, and electronic

Q3. What is Ohm law
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Ohm's Law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• It was formulated by German...read more

Q4. What is the voltage?
Ans. 
Voltage is the difference in electric potential between two points, measured in volts.
• Voltage is the potential difference between two points in an electrical circuit

• It is measured in volts (V)

• Voltage is responsible for the flow of current in a circuit

• Higher voltage means more potential energy available to move electrons

• Examples: 120V in household outlets, 12V in car batteries

Q5. Whats is the drift Velocity?
Ans. 
Drift velocity is the average velocity of charge carriers in a particular direction under the influence of an electric field.
• Drift velocity is a result of the electric field applied to a conductor.

• It is typically very small, on the order of millimeters per second.

• Drift velocity is influenced by the material of the conductor and the strength of the electric field.

• It is an important concept in understanding current flow
