Electronic Principles
Assuming 100% efficiency, what is the power being applied to the primary winding of the transformer described in the above question?
Primary-cell batteries must be recharged at a much slower rate that secondary-cell batteries
Primary-cell batteries can be recharged and used many times, whereas secondary-cell batteries cannot be properly recharged
None of these
Primary-cell batteries use chemical cells, whereas secondary-cell batteries use an alternative energy source, such as thermal or magnetic energy, to supplement their outputs
Secondary-cell batteries can be recharged and used many times, whereas primary-cell batteries cannot be properly recharged
