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?
