First, this statement stands as long as voltage is constant. If you held the current constant then power would increase as resistance increases.
V=IR. For a fixed voltage if you increase the resistance (R) then the current (I) will decrease - following the formula.
Power = VI so as the resistance increases the value of VI (power) decreases as V is constant and I gets smaller.
Therefore the power is decreasing as the resistance increases (when voltage is held constant).
Hope this helps.
What else can I help you with?
Does the current ina circuit increase with increase in temperature?
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.
If the resistance of a load increases will the current increase or decrease?
Well, isn't that just a happy little question! When the resistance of a load increases, the current flowing through it will decrease. It's like adding more trees to a peaceful forest scene - the flow slows down, but everything still finds its balance in the end. Just remember, every change brings new opportunities for beauty and understanding.
When resistance decreases what happens to current?
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
What will happen to the ammeter reading if the resistance is increased?
The current decreases due to I=V/R. The ammeter reading will decrease as R is increased.
When an ammeter is connected to measure current circuit current will decrease sightly because R total decreases after the meter is inserted?
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
Does the current ina circuit increase with increase in temperature?
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.
Does heating a metal wire increase or decrease its electrical resistance?
it so increases it
When the temperature increases thermistor resistance decreases?
Yes, that's correct. In a thermistor, which is a type of temperature-sensitive resistor, the resistance decreases as the temperature increases. This is because the conductivity of the thermistor material increases with temperature, causing the resistance to decrease.
Why does the resistance of a semiconducting material decrease when the temperature increases?
The no of electrons in the conduction band increases when the temperature of the semiconductor material increases. therefore resistance decreases. This is also know as "Negative temperature coefficient"
When resistance increases what occur to power?
It decreases
Why does the resistance of a thermistor decrease as the temperature rises?
Some materials have negative temperature coefficients of resistance, and some have positive temperature coefficients. Carbon is an example of a substance with a negative thermal coefficient of resistance, so it's resistance will decrease as it gets hotter.
How does temperature affect the resistance of conducting materials?
As temperature increases, the resistance of conducting materials also typically increases. This is because as temperature rises, the atoms in the material vibrate more, leading to more collisions with electrons, which in turn increases resistance. Conversely, as temperature decreases, resistance tends to decrease as well.
What happens the power consumption of a circuit as its resistance increases?
😉
The resistance of an extension cord varies directly with the length of the cord?
This means that as the length of the extension cord increases, the resistance also increases. Similarly, if the length decreases, the resistance will decrease as well. This relationship is described by the equation R = kL, where R is the resistance, L is the length, and k is a constant.
If the resistance of a load increases will the current increase or decrease?
Well, isn't that just a happy little question! When the resistance of a load increases, the current flowing through it will decrease. It's like adding more trees to a peaceful forest scene - the flow slows down, but everything still finds its balance in the end. Just remember, every change brings new opportunities for beauty and understanding.
What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
