Basic Concepts of Ohm's Law

• Ohm's Law is a fundamental principle in electricity and magnetism.
• Establishes the relationship between electric current, resistance and voltage in a circuit.
• Electrical current⁤ (I) is measured in amperes (A), resistance (R) in ohms​ (Ω) ‍and voltage (V)⁣ in ⁤volts (V).
• The mathematical formula that represents Ohm's Law is V = I⁤ * R.
• This means that the voltage in a circuit is equal to the product of the current and the resistance.
• Ohm's Law applies primarily to metallic conductors at constant temperatures.
• It is useful for calculating the current, resistance or voltage in an electrical circuit.
• This law is essential to understanding how electrical and electronic devices work in everyday life.
