if 3 resistances 2,3,4 ohm are connected in series.find equivalent resistance.

a battery of 10V is connected with 5 ohm resistance then find current in this circuit.

when two equal resistances are connected in series and parallel combination. find equivalent resistance in both cases.

A single layer of No. 24 AWG (dia=0.0201 in) commercial iron wire is wound over a ceramic tube whose diameter is 3.25 in. if the total wire resistance is 41 ohms, determine the number of turns.

1. A coil of annealed copper wire has 820 turns, the average length of which is 9 in. If the diameter of the wire is 32 mils, calculate the total resistance of the coil at 200C.
