Q3. Voltage devider rule
Ans. 
The voltage divider rule is used to calculate the voltage across a resistor in a series circuit.
• The voltage divider rule states that the voltage across a resistor in a series circuit is proportional to its resistance.

• The formula for the voltage divider rule is Vout = Vin * (R2 / (R1 + R2)), where Vout is the voltage across R2, Vin is the input voltage, R1 is the resistance before R2, and R2 is the resistance across whi...read more

Q4. Ohms law in detail and formula
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 its resistance.
• Ohm's law is expressed by the formula: V = I * R, where V is the voltage, I is the current, and R is the resistance.

• The law was named after the German physicist Georg Simon Ohm, who first formulated it in 1827.

• Ohm's law is fundamental in understanding and a...read more
