Two resistors are connected in parallel and are connected across a 40 volt battery. If each resistor is 1000 ohms, the total battery current is:

  a.   40 ampere

  b.   40 milliampere

  c.   80 ampere

  d.   80 milliampere
Your answer "a" is not correct. "d" is the right answer.

Current through one resistor:
I = E / R
= 40 / 1000
= 40 mA
As there are two resistors, there will be twice the current.
