Three 5 ohm resistors connected in parallel have a potential difference of 60V applied across the combination. The current in each resistor is 

A. 4A 

B. 36A 

C. 12A 

D. 24A 

E. 10A.

ANSWER: Option C

EXPLANATION: You should note that in a parallel arrangement, Voltage is always the same as with the case of current being the same in series arrangements.

So, to know the current in each resistor, just the ohmic equation;. V= IR and make the current (I),  the subject of the formula!
