To construct a battery with a current of 6 a, you would connect six 1 a cells
a. in parallel.
b. to a ground.
c. in series-parallel.
d. in series.

i chose "d" but the answer was actually "a". can someone better explain that to me?

A. in parallel.

Explanation:

In the series circuit, the current is the same for all of the elements in the circuit. This means that current in a resistor is the same as in every other resistor

Mathematically,

I = = = ... =

In the parallel circuit, the total current is the sum of the currents through the individual components

Mathematically,

= + + ... +

For the series circuit, connecting six 1 A cells yields

I = = = = = = = 1 A

For the parallel circuit, connecting six 1 A cells yields

= + + + + + = (1 + 1 + 1 + 1 + 1 +1) A

= 6 A

It therefore follows that the answer is option A. in parallel.
