Because tvs require more voltage than is found in normal household current, what is built into them? a induction batteries b step-up transformers c step-down transformers d secondary generators

The answer is B. Step-up transformers increase the voltage of an electric power line but reduce the current. This is because the power of the electricity remains the same but voltage and current can be changed in accordance with the following formulae:

P = IV where:

P = power

I = current

V = voltage

it about 600 mph from what i calculated

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
