Question

FOUR RESISTOR OF RESISTANCE 1ohms,5ohms,3ohms,and 4ohms.are connected In Parallel.calculate The Value Of Resistance
The easy way for resistances in parallel is to think the inverse of resistance, conductance. In parallel, conductances add
C= 1/R = 1/1 + 1/5 + 1/3 + 1/4
= 180/180 + 36/180 + 60/180 + 45/180
= 321/180
so
R = 1/C = 180/321 = 0.561 Ohms
