To raise the temperature difference without changing the current, you can increase the resistance in the circuit. This can be done by adding additional resistors in series, using a material with higher resistance, or by adjusting the configuration of the circuit to increase the overall resistance. By increasing the resistance, the same current will produce a greater voltage drop across the resistors, resulting in a higher temperature difference.

Which heat changes the state of a substance without changing its temperature?
Latent heat is the heat that causes a change in the state of a substance without changing its temperature. This process involves absorbing or releasing energy to break or form intermolecular forces between particles.
What is a property of a materials that can be measured without changing the identity of the material?
Density is a property of a material that can be measured without changing the identity of the material. It is the mass per unit volume of a substance and remains constant for a specific material at a given temperature and pressure.
What is the difference in specefic heat and latent heat?
Specific heat is the amount of heat required to raise the temperature of a substance by 1 degree Celsius, while latent heat is the heat absorbed or released during a phase change at a constant temperature. Specific heat is associated with changing the temperature of a substance, while latent heat is associated with changing the phase of a substance.
The amount of energy involved in melting a substance without changing its temperature is called the?
latent heat of fusion. It represents the energy required to change a solid substance into a liquid at its melting point, without changing its temperature.
Can you add thermal energy to an object without increasing its temperature?
Yes, it is possible to add thermal energy to an object without increasing its temperature by changing its phase. For example, when ice is melting, thermal energy is being absorbed to break the bonds between water molecules without a change in temperature.
Can proteins absorb or lose heat without changing temperature?
Yes, proteins can absorb or release heat without changing temperature through a process called conformational changes. This involves altering the spatial arrangement of the protein's structure which involves absorbing or releasing energy.
Rocks can melt without changing temperature when the pressure exerted on them is .?
Increase
When can voltage be induced but not current?
"Induced" is the verb you are looking for. A current is induced in the secondary circuit by the current in the first changing, provided both conductors are close enough for the driving current's electro-magnetic field to enclose the second conductor. Note that word "changing". Direct current produces a field but that remains constant and does not induce a secondary current, as a.c. does.
Can you increase current in a circuit without change in resistance and voltage?
no it is not possibleAnswerYes, by changing the voltage OR the resistance.
How can you decrease the pressure of gas in a container without changing the volume of the gas?
You could lower the temperature.
Is saturated a soulution that contains all solute and can be dissolved with out changing temperature?
A saturated solution contains the maximum amount of solute that can be dissolved at a given temperature. If a solution is saturated, adding more solute will not dissolve into the solution without changing the temperature.
What energy is required to create a phase change without changing the temperature?
The energy required to create a phase change without changing the temperature is known as latent heat. This energy is needed to break the intermolecular forces holding the molecules in a particular phase, such as solid to liquid or liquid to gas, without increasing the temperature of the substance.
What is the energy required to change a substance from a solid to a liquid WITHOUT changing it's temperature?
magic of coarse!
What could you do if you wanted to reduce the volume of gas without changing the temperature?
You could let the gas flow !
What property can be observed without changing the identity of matter?
A physical property, such as color, shape, density, or temperature, can be observed without changing the identity of matter. These properties describe the characteristics of a substance and can be measured or observed without altering the substance itself.
How do you make ice last longer in a cup without changing the temperature?
you put it in a refridgerator or a cooler which ever works for you
