What is the effect of the temperature on the resistance of wire?
The resistance of most conductors increases with increase in temperature.
The resistance of most conductors increases with increase in temperature.
See lessResistance depends upon the length of the conductor. How?
Resistance is directly proportional to the length of the conductor, provided its area of cross section is constant.

See lessHow does net resistance change in parallel connection of resistors?
Net resistance decreases when resistors are connected in parallel.
Net resistance decreases when resistors are connected in parallel.
