Find the equivalent resistance between A and B

Name the material which is the best conductor of electricity.

You are supplied with a number of 100 Ω resistors. How could you combine some of these resistors to make a 250 Ω resistor?
State how are the two resistors joined with a battery when equivalent resistance is more than either of the two resistances.
In the circuit shown below, calculate the equivalent resistance between the points (i) A and B, (ii) C and D.
Two lamps of resistance 30Ω and 20Ω respectively are connected in series in a 110V circuit. Calculate:
(i) the total resistance in the circuit
(ii) the current in the circuit, and
(iii) the voltage drop across each lamp.
What should be the length of a nickel wire of area of cross-section 3 mm2 used for making a rheostat of 750 ohm? (ρ of nickle = 0.069 Ohm mm2/m)
If the current I through a resistor is increased by 100% (assume that temperature remains unchanged), the increase in power dissipated will be:
