Draw a parallel circuit with 3 loops. There is an ammeter in each loop and one next to the battery. If the one next to the battery gives a reading of 12A what will the other say? Stretch - what will happen to the 12A reading if another loop is added?

Each ammeter in the loops would read 4A and if other loop is added the loop ammeter would read 3A

Explanation:

The formula for current in parallel is;

The total current value from the source battery is 12A, so the three loops with no load would read;

= 12 / 3 = 4A

When another loop is added to the circuit, the total current would be divided by the four loop which will give a value of 3A for each loop.

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

i think that c)gold was found there

but i am not sure
