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

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
