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

Q4. What's current unit
Ans. 
The current unit is the ampere (A), which measures the flow of electric charge.
• The ampere is named after the French physicist André-Marie Ampère.

• Current is the rate at which electric charge flows through a conductor.

• Other common units for current include milliamperes (mA) and microamperes (μA).

Q2. Why soft starter use against star -delta starter for motor start & run .
Ans. 
Soft starters are preferred over star-delta starters for motor start and run due to their ability to reduce inrush current and provide smoother acceleration.
• Soft starters provide a gradual increase in voltage to the motor, reducing inrush current and mechanical stress on the motor.

• Star-delta starters provide a sudden increase in voltage, resulting in high inrush current and mechanical stress on the motor.

• Soft starters ...read more
