Explain what you understand from 'Ohm's law'. In about 50 words, explain practical consequences of Ohm's law, with examples from real life, as needed.

Expert Solution

Ohm's law is given as

V = IR

It means current through a conductor between two points is directly proportional to the voltage across the two points. Ohm’s law helps us in determining voltage, current or resistance of an electric circuit when the other two quantities are known.

Practicality of Ohm's law

1) Look at the ceiling fan - we can control the speed of the fan by rotating the speed control knob. So, what's happening behind the scenes ?? Here, the current flowing through the fan is controlled by regulating the resistance through the regulator. so, more the resistance, less the current

2) Fuse devices - You might have seen those tube like small transparent device found usually on the back of every appliance. Those are called fuse. They are protection components that limit the amount of current flowing through the circuit and to establish a certain amount of voltage. They also work on the basis of Ohm's law

With respect to Ohm's Law, explain in your own words what is meant when it is said that there is "a linear response between voltage and current." Name a specific device in which Ohm's Law is a good description of the relationship between current and voltage, and one for which it is not. Do your best to explain this failure in terms of the basic properties of electrons flowing through a conducting material. Describe the temperature response of resistors in...

1. Answer the following question with Ohm's law. a. explain why Ohm's law implies that charges in circuit move at constant velocity. b. A charge passing through a potential drop will accelerate under the force of the associated electric field, F field=qE. However, a charge moving in a wire experiences a "drag force" that is proportional to its velocity, F drag= c x v, and points opposite to the direction of motion. Explain how the combination of these two forces...

According to Ohm's Law, if you have a simple circuit (Figure 2), what happens to the voltage and current of the resistor as the resistance increases? If a 100 Ohm resistor is attached to a 5 V battery, how much current flows through the resistor? If a wire's length is cut in half, what happens to the wire's resistance? If a wire's area is reduced by half, what happens to the wire's resistance? If the diameter and length of a wire are split in...
