Someone please explain.
Half the time current is flowing from one set of 2 diodes and the other two for the next half. So basically the current is available only for half time period for any diode. While current is available for whole time at load. In this manner isn't each diode carrying half of load DC current?

Dear, here input given to the diode is dc (not ac) that's why through the whole time period a pair of diode is forward biases and others in reverse biases. So current through pair of diode which is in forward biases is equal to load and others have zero.

In series configuration current is same, so during the positive half cycle of sine wave diode d1 and d3 will conduct through the load resister, so current will be same same thing commensurate for the the negative half cycle of the sine wave.

AC - alternating current, its polarity will change with cycle (+ or -).
DC - Direct Current fixed.

Apply the Ohm's law. Some of all the currents are equal to the total current.
