State how resistance, current and voltage generally change when temperature increases? ?

When temperature increases, the resistance of a material typically increases as well. This is because the atoms in the material vibrate more vigorously, causing more collisions with the electrons and hindering their flow.

As resistance increases, the current flowing through the material decreases, as described by Ohm's Law (I = V/R).

Similarly, as resistance increases and current decreases, the voltage across the material also decreases. This is because the voltage is directly proportional to the current and resistance in a circuit.

Overall, when temperature increases, resistance increases, current decreases, and voltage decreases.

Resistance: Generally increases with increasing temperature.
Current: Generally decreases with increasing temperature.
Voltage: Remains relatively constant with changing temperature.
