What is the formula to calculate resistance?
What is the formula to calculate resistance?
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
What is the law of resistance?
The following are the main laws of resistance: (i) Resistance of a conductor is directly proportional to its length, provided temperature and other physical conditions remain unchanged. (ii) Resistance of a conductor is inversely proportional to its area of cross section, other conditions remaining the same.
What are types of resistance?
Resistors can be broadly of two types. Fixed Resistors and Variable Resistors. resistors. A fixed resistor is one for which the value of its resistance is specified and cannot be varied in general.
What are the 3 types of resistance training?
Summary
- Resistance training increases muscle strength by making your muscles work against a weight or force.
- Different forms of resistance training include using free weights, weight machines, resistance bands and your own body weight.
- A beginner needs to train two or three times per week to gain the maximum benefit.
What are the four types of resistance?
The four main resistance forces are objects with mass, inertia, and momentum; friction; gravity; and air resistance. Objects with mass are able to provide resistance by colliding with other objects.
What is psychotherapy resistance?
Resistance, in psychoanalysis, refers to oppositional behavior when an individual’s unconscious defenses of the ego are threatened by an external source. This would be for the purpose of inhibiting the revelation of any repressed information from within the unconscious mind.
How do you address resistance in therapy?
“Don’t blame the client, and don’t blame the people they think are creating their problems.” “Always treat the resistance with respect,” Mitchell says. “The client has a reason for what they just said, (so) respect it.” “Seek emotionally compelling reasons for change,” Mitchell says.
When an object has its motion change the causes generally?
Answer Expert Verified When an object has its motion changed, the cause is generally an external force. The answer is letter A. It follows Newton’s second law of motion wherein a body is at rest and remains at rest without an external force applied to move the body.
What are 5 ways motion can change?
What are five ways a force can change motion? Answer: The action by a force can cause an object to move or speed up , to slow down , to stop, or to change direction.
What are 5 ways an object’s motion can change?
The action from a force can cause an object to move or speed up (accelerate), to slow down (decelerate), to stop, or to change direction.
What is the change in position of an object called?
In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. One can also speak of motion of images, shapes, and boundaries.
How far an object travels is called?
The speed of an object is the distance the object travels in one unit of time. To calculate the speed of an object, divide the distance the object travels by the amount of time it takes to travel that distance.
How can we prove an object is moving?
An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you use a reference point. If an object’s distance from another object [reference point] is changing. A place or object used for comparison to determine if something is in motion.
What if I push an object which is already moving horizontally?
Thus, force would cause. acceleration in horizontal motion.
Is it possible for an object to be in motion if no net force is acting on it explain?
Is it possible for an object to be in motion if no net force is acting on it? yes it is possible because when the net force is zero and acceleration is zero. so if the object has some constant velocity it continues with the same velocity until it has some external acceleration.
Which of the following is the tendency of an object to maintain its state of motion?
inertia
