When you push something heavy the resistance you feel decreases as the body starts moving explain what happens?
This is caused by what can be called "stick-slip". Once the initial friction is overcome it is easier to keep an object in constant motion than it was to get it to move from standstill. Mostly this involves the Van de Waals forces (electrostatic forces) that arise when objects are very close to each other.
What else can I help you with?
When you push something heavy the ressistance you feel decreases as the body starts moving explain what happens?
When you push something heavy, the resistance you feel decreases as the object starts moving because static friction transitions to kinetic friction. Static friction is the force that keeps an object at rest, while kinetic friction is the force that opposes motion once the object starts moving. As the object overcomes static friction and transitions to kinetic friction, the resistance you feel decreases.
What happens to the current if the conductance decreases?
If conductance decreases, the current flowing through the circuit will also decrease. Conductance is the inverse of resistance, so decreasing conductance means increasing resistance, which impedes the flow of current.
What happens to the resistance of a wire as its diameter increase?
As the diameter of a wire increases, its resistance decreases. This is because there is more cross-sectional area available for the flow of electrons, resulting in less opposition to the flow of current and thus lower resistance.
What happens to the resistance of a filament if it is replaced by a thicker wire?
If a filament is replaced by a thicker wire, the resistance of the circuit will decrease. Thicker wires have lower resistance because they offer less resistance to the flow of electric current compared to thinner wires of the same material and length.
Does resistance increase as the cross-sectional area of the wire?
the resistance can never increase or decrease....... (you can't open the resistor and take out the something and make the resistance increase or decrease)AnswerSince resistance is directly proportional to the length of a conductor, increasing the length of a wire will increase its resistance. For example, if you double its length, you will double its resistance.
What happens to the current as the resistance decreases?
it increases
What happens to the resistance of a metal when it is heated?
its resistence considerably decreases

What happens in a circuit when the resistance gets greater?
Flow of current decreases proportionately.
What happens when a part of a parallel circuit is disconnected?
current decreases and resistance increases
What happens to the power of an electric circuit of the resistance is decreased?
if the resistance is decreased and the current stays the same, then the power decreases.
What happens to the current in a circuit if the resistance is increase?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happens to the current in the circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happens to the current if the conductance decreases?
If conductance decreases, the current flowing through the circuit will also decrease. Conductance is the inverse of resistance, so decreasing conductance means increasing resistance, which impedes the flow of current.
How does LDR work for street lights?
LDRs work when the light intensity increases, the resistance decreases. If this happens, I think the amount of current is too little so triggers something which turns the street lamps on. I'm not quite sure if this is what happens.
What happens to its resistance when an electrical device is heated?
That will depend on the temperature coefficient of resistance of the device, which could be positive (i.e. resistance increases with increasing temperature), negative (i.e. resistance decreases with increasing temperature), or zero (i.e. resistance is unaffected by temperature changes).
What happens if a thermistor is heated?
the thermistors respond negatively to the temperature and their resistance decreases with the increase in temperature. Since the resistance of thermistors is dependent on the temperature, they can be connected in the electrical circuit to measure the temperature of the body.
