If resistance goes up in a circuit, the current will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, meaning that as resistance increases, current decreases.
Current is directly proportional to the applied voltage and inversely proportional to the resistance in the circuit. Short form, resistance goes up current goes down, resistance goes down current goes down.This answer is incorrect.First of all, resistance is not affected by a change in voltage or in current. Resistance is only affected by the length, cross-sectional area, and resistivity of the conductor (and, indirectly, by temperature which affects resistivity).Ohm's Law makes no mention of resistance. It simply states that the current flowing in a circuit is proportional to the applied voltage, providing external factors, such as temperature, remain constant.Since current is proportional to voltage, it must be equal to a constant times voltage. This constant is called conductance, which is the reciprocal of resistance, so the so-called 'Ohm's Law formula' is usually shown as I = V/R. But it's important to remember that the resistance, R, is a constant and does not change if V or I changes.
Well, I am also doing this same question and its all about resistance. Resistance is when the electrons flow around a circuit and they collide with ions. These electrons transfer energy to the ions, which consequently get hot and move more so the resistance increases :) So the thicker the wire is, the less resistance it would have because there are more choices of pathways for the electrons can take without colliding with the ions. Therefore less resistance, more current needed to melt the wire. So the thicker the wire is, the more current is needed to melt it
The resistance of a filament depends on the current flowing through it because as current flows through the filament, it heats up due to the electrical energy converting into heat energy. This increase in temperature causes the resistance of the filament to increase, resulting in a higher overall resistance in the circuit.
Wires warm up when an electric current flows through them due to the resistance in the wire. The resistance converts some of the electrical energy into heat, causing the wire to warm up. This is described by Ohm's Law, which states that the heat generated is directly proportional to the resistance and the square of the current flowing through the wire.
The current is doing work against the resistance of the material which makes up the heating element.Because it has resistance.-- Whenever electric current flows through a resistance, it loses energyequal to (current-squared) x (resistance).-- When we connect components in an electrical circuit, we use wire withthe least possible resistance, so as not to lose energy in the wiring.-- When we want to warm up the lab, we use wire with significant resistance,in order to have it dissipate significant energy and radiate heat.
down
Resistance in a wire causes a decrease in the flow of current. This is because resistance impedes the movement of charge carriers through the wire, leading to a reduction in the overall current. Ohm's Law (V = I x R) shows the relationship between voltage, current, and resistance in a circuit.
Ohms' law says if voltage stays constant resistance controls the current flow. Resistance goes up, current goes down. E/I*R.
v = i*RIf i goes down then R must go up (assuming v remains the same).AnwerCompletely impractical question. Resistance is not directly affected by voltage or current, so what you describe won't happen!
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
because you sweat.
A negative resistance region is where the current goes up while the voltage goes down, or vice versa. This is a characteristic of the esaki or tunnel diode, when it is in its tunnel region.
In that case, it is more difficult for charge to flow; the total current will decrease.
It varies. On some items resistance goes up, some it goes down when temperature goes up.
Ohm's law states that I = V/R, where I is current in amperes, V is difference potential in volts, and R is resistance in ohms. If I goes up, by relation, either V increases or R drops or both occur. Correspondingly, R = V/I, so if V stays static and I increases, R must decrease.?æ
because at start the motor draws larger quantity of current and this may affected the rotor windings in order to limit current always resistance is connected.
Voltage is the electrical pressure in a circuitAmperes (amps) are the measure of electrical current in a circuitOhms are the measurements of resistance in a circuitCurrent is essentially how fast electrons are moving in a circuitResistance is what impedes the electrical current, and can be found in the wire or various loads in a circuitHope this helps!
