Question

If four 90  resistors are connected in series across an 18 V source, the current equals ___.-A-50 mAB-0.2 AC-5 AD-20 A-A-50 mA

APTITUDE CRACK · Accepted Answer

The correct option is  A 50 mA  By Ohm's law, V = IR. I = V/R Given, Four 90 ohm resisters in series. So, R = ( R1 + R2 + R3 + R4) = 4 x 90 = 360 ohms. Therefore, I = 18/360 = 0.05 A [or] 50 milli amps.
