Get instant solutions, detailed explanations, and build exam confidence with questions in the style of MYP examiners.
In large-scale commercial power stations, which component is typically part of the 'rotor' that is physically spun to generate electricity?
If a technician cranks a hand-powered AC generator faster, what happens to the electrical output observed on an oscilloscope?
In a transformer, why must the current in the primary coil be alternating current (AC) rather than steady direct current (DC)?
For mains electricity transmission over long distances, AC is preferred over DC primarily because:
Why does the output of a simple AC generator reverse its direction every half turn?
In a 100% efficient step-up transformer, the output voltage is times greater than the input voltage. How does the output current compare to the input current ?
An ideal step-down transformer reduces voltage from AC to AC. How does the current in the secondary coil () compare to the current in the primary coil ()?
During one complete rotation of a single coil within a simple AC generator, how many times does the induced voltage reach its peak magnitude (either positive or negative)?
Why is a steady direct current (DC) unable to induce a continuous voltage in the secondary coil of a standard transformer?
A transformer is used to reduce a mains voltage of AC down to AC. What is the required ratio of the number of turns on the primary coil () to the number of turns on the secondary coil ()?
