A transformer has input voltage and current of 12 V and 4 A
respectively, and an output
current of 0.8 A. If there are 1177 turns turns on the
secondary side of the transformer, how many
turns are on the primary side? 4 significant digits please.

Explanation:

It is given that,

Input voltage,

Input current,

Output current,

Number of turns in the secondary side of transformer,

We need to find the number of turns in the primary side of the transformer. The current to the number of turns in the input and output is given by :

Substituting all the above values

So,

So, the number of turns in primary side of the transformer is 5885.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
