Three equal resistances when combined in series are equivalent to 90 ohm. Their equivalent resistance when combined in parallel will be:

A uniform wire of resistance R and length L is cut into four equal parts , each of lengths L/4, which are then connected in parallel combination. The effective resistance of the combination. The effective resistance of the combination will be

A combination consists of three resistors in series. Four similar sets are connected in parallel. If the resistance of each resistor is 2 Omega , find the resistance of this combination.

Tweve identical resistance each of resistance R are joined to form a cube as shown in figure. Find resistance of the combination across AB
