Using Ohm's Law E=IR, we would need four 8 ohm bulbs in parallel to draw a total circuit current (I sub t) of 2 amps. Each of the four branches would have .5 amps flowing through the bulb.

what will be the emf of the battery when Four cells each of emf E are joined in parallel to form a battery?
E. Joined in parallel, the voltage (or electromotive force, "emf") isn't additive. You'd get four times the current, or four times the life of a single battery, but it would have the same voltage.

How do you wire two 12 volt batteries together?
You can either wire them in series, connecting the positive of one battery to the negative of the other and then having two separate leads as the power source (one from each battery).Or, you can wire them in parallel, with the two negatives joined (to a common negative lead), and the two positive terminals joined (with a common positive terminal).NOTE: If you don't know what you are doing look for a diagram or ask someone for assistance, if the batteries are wired incorrectly, or short they can cause a fire or even explode.
