FAQs on Ohm's Law (Easy Explanation) Video Lecture - Class 10

1. What is Ohm's Law?
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. It can be mathematically represented as I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.
2. What is the significance of Ohm's Law?
Ans. Ohm's Law is of great importance in the field of electricity and electronics. It allows us to calculate the current flowing through a circuit, given the voltage and resistance, or calculate the resistance, given the voltage and current. It serves as a fundamental principle for understanding and analyzing electrical circuits.
3. How can Ohm's Law be applied in real-life situations?
Ans. Ohm's Law can be applied in various real-life situations, such as calculating the current flowing through a household appliance, determining the resistance of a wire, designing circuits for electronic devices, troubleshooting electrical problems, and understanding the behavior of electrical components.
4. What are the units used in Ohm's Law equation?
Ans. The units used in Ohm's Law equation are as follows: - Current (I) is measured in amperes (A). - Voltage (V) is measured in volts (V). - Resistance (R) is measured in ohms (Ω).
5. Can Ohm's Law be applied to any type of circuit?
Ans. Yes, Ohm's Law can be applied to any type of circuit, whether it is a simple series circuit, a parallel circuit, or a combination of both. However, it assumes that the circuit components are linear and obey Ohm's Law. In non-linear circuits, where the resistance changes with voltage or current, Ohm's Law may not be directly applicable.
