What are the forces of a stationary boat?
The forces acting on a stationary boat in still water are gravity acting downwards, buoyancy acting upwards, and drag acting to oppose any external forces like wind or current. These forces are balanced when the boat is stationary.
''Ohm's law is the tendency for material to oppose the flow of electrons''is this true?
No, that statement is not accurate. Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, given a constant temperature. It describes the relationship between current, voltage, and resistance in a circuit.
How can we use Lenz's Law to determine the direction of induced current in each case?
Lenz's Law states that the direction of the induced current in a circuit is such that it opposes the change in magnetic flux that caused it. By applying Lenz's Law, we can determine the direction of the induced current by considering the direction of the changing magnetic field and the direction of the induced current that would oppose that change.
What are two forces that oppose flight?
Gravity and drag are two forces that oppose flight. Gravity pulls the aircraft downward, while drag slows the aircraft's forward movement. Both forces must be overcome for an object to achieve and maintain flight.
What are the 2 forces that oppose motion?
The two forces that oppose motion are friction and air resistance. Friction is the force that acts opposite to the direction of motion when two surfaces are in contact, while air resistance is the force that opposes an object's motion through the air.
What is the role of inductance in lcr circuit?
oppose changes in current flow.
Total opposition to current flow in an AC circuit?
I oppose alternating current. Direct is the only way for me. That is 1 in opposition.
What is inductor functioning?
Actually Inductor oppose the change of current in the circuit..... Acts like a short circuit in steady state condition....
What is an object in an electric circuit that resists the flow of electrons?
A special kind of resistor can oppose the flow of an electrical current.
Why does the current immediately increase in current after reaching a certain voltage rather than a gradual current increase?
It depends on the nature of the circuit. In a purely-resistive circuit, the current would rise immediately because resistance merely limits its value, it doesn't oppose any change in current. But in a resistive-inductive circuit, for example, the inductive component opposes any change in current, so the current will rise more gradually.
What are forces that oppose motion?
Friction
Why is circuit current reduced when a capacitors added to the circuit?
In the case of an a.c. circuit, capacitors oppose current because of their capactive reactance, expressed in ohms. Capacitive reactance is inversely-proportional to the capacitance of the capactor and to the frequency of the supply. So, adding a capacitor is series with an existing load will reduce the load current. On the other hand, adding a capacitor in parallel with an existing load will decrease the load current.
What are the forces of a stationary boat?
The forces acting on a stationary boat in still water are gravity acting downwards, buoyancy acting upwards, and drag acting to oppose any external forces like wind or current. These forces are balanced when the boat is stationary.
What is induction of electric current?
According to Farady's law, whenever the flux linking with the coil changes, emf will induce in that coil.Actually the material should oppose the flux changes, that opposition is the induced current. Induced current will set own flux, opposite to that of the flux changes.For further details, refer lenz law.
What happens when an inductive coil is first connected across a dc supply?
Inductors tend to oppose a change in current, so the initial current is low, and rises according to the RC time constant of the circuit to a final value.
Who formulated a law for determining the direction of the induced current in a conductor?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. If the conductor into which that voltage is induced forms a complete circuit, then a current will result. But it's the voltage that's induced, NOT the current! The direction of the induced voltage is explained by Lenz's Law which, in simple terms, tells us that the direction of the inducted voltage is always such that it will oppose the change in current that causes it. So the induced voltage will oppose any increase in current, but will act in the same direction as a reduction in current.
What effect in resistace to oppose the current?
Increase resistance lowers current
