According to Ohm's law if V is constant?
Ohm's Law describes the relationship between the voltage (potential difference) across the ends of some conductors and the resulting current through those conductors for variations in voltage. If the voltage is constant, then Ohm's Law is irrelevant.
What is constant in ohms law?
Ohm's original law was 'The potential difference across a conductor is proportional to the current flowing through it, provided physical conditions such as temperature remain constant.'Today Ohm's law is expressed as E = IR or sometimes V = IR,the units being Volts, Amps and Ohms.AnswerOhm's Law ('the current flowing along a conductor, at constant temperature, is directly proportional to the potential difference across that conductor') only applies when the resistance of the conductor is constant so, when verifying Ohm's Law, the temperature must be kept constant, in order to keep the resistance constant.It should be pointed out that the ratio of voltage (U) to current (R) is called resistance (R), and the resistance of a circuit can be found from the equation, R = U/I whether Ohm's Law applies or not -but Ohm's Law itself only applies when the ratio is constant over a range of voltage variation.
Which states that the ratio of voltage to current in a material is constant which is the resistance of the material?
Ohm's Law
Using Ohm's Law explain how voltage changes in relation to current assuming that resistance remains constant?
how do you use ohms law express conductance in terms of current and voltage?
What is the main objection of ohm's law in measuring resistance?
Temperature. Ohms law is applicable to measure resistance of an element at constant temperature only.
What is the Henry's law constant for Carbon Dioxide at 20 degrees Celsius?
Henry's law constant for Carbon Dioxide at 20 degrees Celsius is: 1,6*10^3 ATM
What volume is occupied by 2.0g He at 25 degrees celsius and 775 mmHg?
A fixed quantity of gas at a constant pressure exhibits a temperature of 27 degrees Celsius and occupies a volume of 10.0 L. Use Charles's law to calculate: the temperature of the gas in degrees Celsius in atmospheres if the volume is increased to 16.0 L
When the pressure on a gas increases at constant temperature its volume?
decreases
Do this with degrees Celsius in solving problems with Charles law?
convert
When ice melts at 0 degrees Celsius is it a theory or law?
No
Does steam at 100 degrees celsius obeys Boyle's Law?
Yes it does
Two identical blocks of iron one at 10 degrees celsius and the other at 20 degrees celsius are put in contact suppose the cooler block cools to 5 degrees celsius and the warmer block warms to 25?
Violation of 2nd Law
Rigid container holds hydrogen gas at a pressure of 3.0 atmospheres and a temperature of 2 degrees Celsius Whatwill bethe pressure if the temperature is raised to 10 degrees Celsius?
Rigid container holds hydrogen gas at a pressure of 3.0 atmospheres and a temperature of 2 degrees Celsius. The pressure if the temperature is raised to 10 degrees Celsius will be 15 atmospheres based on the law of pressure for gas.
30 cubic meters of argon gas is kept under constant pressure the gas is heated from 10.0 degrees Celsius to 293 degrees celsius what is the new volume of the gas?
8 is the new volume of the gas.
How can you calculate the vapour pressure of water over the solution at 90 degrees Celsius vapour pressure of water at 90 degrees Celsius is 525.8mmHg?
If this solution is a mixture you would use Henry's or Raoult's Law. If this is pure water then the answer is already in the question.
How do you calculate the pressure of a gas in a cylinder with avolume of 15.0 L and filled with 50.0 g of gas at 25 degrees celsius?
50.0 grams of what gas? This is the ideal gas law. Pressure * Volume = moles gas * the R constant * temperature in Kelvin PV = nRT
500cm3 of ideal gas at 40 degrees Celsius and 200kpa absolute is compressed to 250cm3 and cooled to 20 degrees Celsius.What is the final absolute pressure?
Assuming the amount of gas remains constant, we can use the ideal gas law to calculate the final absolute pressure. The initial pressure (P1) is 200 kPa and the final volume (V2) is 250 cm3. The initial temperature (T1) is 40 degrees Celsius or 313.15 Kelvin, and the final temperature (T2) is 20 degrees Celsius or 293.15 Kelvin. Using the equation (P1 * V1) / T1 = (P2 * V2) / T2, we can solve for the final absolute pressure (P2), which is approximately 400 kPa.
