Double the area means half the resistance.
Resistance = resistivity times length / area. Resistivity is a property of the material only.
Increases
resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
The answer to this depends on the material from which the resistance is made. For most materials resistance increases with increasing temperature. This is referred to as having a "positive temperature coefficient". Some materials have a negative temperature coefficient; these do have uses in electronics.
it increases
😉
Yes, the resistance is directly proportional to length of wire and inversely proportional Area, hence when Length of wire increases the resistance also increases and when Area increases the resistance decreases. This means a thick wire has least amount of Electrical resistance.
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.
Resistance R =p(L /A)i,e Resistance(R) of a conductor will be directly proportional to its length(L) ==> if the length of the conductor increases its resistance also will increase.i,e Resistance(R) of a conductor is inversely proportional to its cross section area(A) ==> if the Area of the conductor increases its resistance also will decrease.
Air resistance will increase when the parachute opens, and the decent of the skydiver will slow down.
When a common ohmic resistor is heated, its resistance typically increases.
current decreases and resistance increases
Resistance is inversely proportional to cross-sectional area. so ,if the thickness of the wire increases, the area of cross-section increases and this results in decrease of the resistance. The resistance R = l p / A where R is the resistance, l is the length of the wire, p(rho) is the electrical resistivity of the material and A is the area of cross section. So R the resistance is inversely proportional to A the area of cross-section. If R increases
The resistance of a wire is directly proportional to its length. This means that as the length of the wire increases, the resistance also increases. This relationship is described by the formula R = ρ * (L/A), where R is resistance, ρ is the resistivity of the material, L is the length of the wire, and A is its cross-sectional area.
The resistance of a wire is inversely proportional to its cross-sectional area. A larger area means there is more space for electrons to flow, reducing the resistance. Conversely, a smaller area restricts electron flow and increases resistance.
