Q1. Current (I) =voltage (V)/Resistance (R)
Ans. 
Ohm's Law states that current is equal to voltage divided by resistance.
• Ohm's Law is a fundamental principle in electrical engineering

• Current (I) is measured in Amperes (A)

• Voltage (V) is measured in Volts (V)

• Resistance (R) is measured in Ohms (Ω)

• The formula I = V/R can be used to calculate current in a circuit

Q2. What it ohm's law
Ans. 
Ohm's law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.

• It is named after German physicist Georg Simon Ohm.

• Ohm's law is fundamental in the field of electrical engineering and is used to analyze and design electrical circuits.

• It help...read more

Q4. Difference between AC and DC
Ans. 
AC stands for alternating current, which changes direction periodically, while DC stands for direct current, which flows in one direction.
• AC changes direction periodically, while DC flows in one direction constantly.

• AC is used in household appliances and power distribution, while DC is used in batteries and electronic devices.

• AC can be easily converted to different voltage levels using transformers, while DC requires m...read more

Q5. How will you calculate current carrying in a conductor ?
Ans. 
Current carrying in a conductor can be calculated using Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R).
• Use Ohm's Law: I = V / R

• Determine the voltage across the conductor

• Find the resistance of the conductor

• Calculate the current flowing through the conductor using the formula
