The effect of temperature on Ohm's Law is that the resistance of most materials changes with temperature, which in turn affects the current and voltage relationship described by Ohm's Law. Specifically:

• Resistance Increase: For most materials, such as metals, resistance increases with temperature. This can lead to higher resistance in a circuit as it heats up, which can reduce current if the voltage remains constant.

• Resistance Decrease: Some materials, like semiconductors, show decreased resistance with increasing temperature. This can lead to increased current if the voltage remains constant.

Ohm's Law itself (V=IR) remains valid, but the value of resistance (R) can change with temperature, altering the relationship between voltage (V) and current (I).

What effect are there when resistance is increased in the size of the current?

Current is inversely proportional to resistance. If you double the resistance, you halve the current. Ohm's Law: Volts = Amps * Ohms Solve for Amps: Amps = Volts / Ohms

When does a thermostor obey ohm's law?

I hope you mean the thermistor. If so,well it does not obey Ohms law. When current flows through the thermistor its temperature start increasing which reduces the resistance of the thermistor. A reduction in resistance at the same supply voltage will cause the current to increase. Thus it's not obeying Ohms law.
