If five equal resistors are connected in series with a 20 V source, and a current of 400 µA is measured, each resistor equals ___.-A-10 kB-50 kC-125 D-20 -A-10 k

Question

If five equal resistors are connected in series with a 20 V source, and a current of 400 &#181;A is measured, each resistor equals ___.-A-10 kB-50 kC-125 D-20 -A-10 k

APTITUDE CRACK · Accepted Answer

A 10 k R = 5R. V= 20V. I = 400*10^ 6A. SO WE KNOW THAT V = IR. SO, 20 = 400*10^ 6*5R. So we will get it as R=10000. That is, R = 10kohms.
