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).

Q1. Transformers working principle
Ans. 
Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.
• Transformers have two coils of wire, known as the primary and secondary coils.

• When an alternating current flows through the primary coil, it creates a changing magnetic field.

• This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy.

• The ratio of the number...read more
