What is the minimum number of 70 -Ohms resistors that must be connected in parallel to produce an equivalent resistance of 13 Ohms or less?

Answer 1

1/13>=k/70

70=>13k
k>70/13
k>6

Answer 2

If you have a curcuit consisting of 4 resistor of egual resistance senses and toltal voltage across all of them is 17v .what is the voltage across each of them?
