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).
