Electronic Principles
What is the turns ratio of a power transformer that shows 50 V at its secondary winding when you apply 150 V to its primary winding?
Primary-cell batteries must be recharged at a much slower rate that secondary-cell batteries
None of these
Primary-cell batteries can be recharged and used many times, whereas secondary-cell batteries cannot be properly recharged
Secondary-cell batteries can be recharged and used many times, whereas primary-cell batteries cannot be properly recharged
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
