Q2. What is the voltage forumola
Ans. 
The voltage formula is used to calculate the voltage in an electrical circuit.
• The voltage formula is V = I * R, where V is the voltage, I is the current, and R is the resistance.

• This formula is derived from Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage and inversely proportional to the resistance.

• By rearranging the formula, we can also calculate current (I ...read more
