Question: four 20 ohm resistors are connected in parallel what is the equivalent resistance




Four ohm 20 resistors connected in parallel , the equivalent resistor will be given as


1/REFF = 1/R1+1/R2+1/R3+1/R4

Therefore 1/REFF= 1/20+1/20+1/20+1/20
1/REFF= 4/20
REFF=5ohm
 The equivalent resistance is therefore 5ohms
