three resistance 3ohm,6ohm,and6ohm are connected in parallel with each other,their effective resistance will be a,less than3 b.greater than 3 but lessthan6 c,equal to3 d,greater than6
The rule for adding resistance in parallel is 1/R = (1/R1)+(1/R2)+(1/R3)...
yes he is right .....and the right choice is "less than 3" ....because interestingly, the equivalent resistance in a parallel combition of resistances is less than the least component resistance that is present in the parallel combination.
Yes, if you add up 1/3 + 1/6 + 1/6 you get 2/3 If you invert this you get 3/2 which is <3
