Problem 31.2: Transformer
Please wait for the animation to completely load.
A transformer is connected to an outlet. The graph shows the input voltage (voltage across the primary) and output voltage (voltage across the secondary and resistor) as a function of time. You can read the resistor value by moving the mouse over the resistor. Restart.
- If the primary has 400 windings, how many windings does the secondary have?
- What is the rms current delivered to the primary?
- How much power is delivered to the resistive load?
