What is the instantaneous voltage of an AC waveform at 225 degrees. Peak Voltage = 20 V Accurate to one decimal place (No UNit) %3D 25- E 20- Vp 20 V 15- 10 5- 90 135 180 225 270 315 160 -10- -15- -20- -25 7voltage (V) Flux Density: SCENCEan eY The strength of magnetic flux in a scrap collector electromagnet is 600 mWb. The diameter of the core is 0.75 m What is the flux density in mT (milli Teslas)? Don't write the unit, juts the number. An AC waveform has been shifted by 45 degrees. It's Peak Voltage is 86 V What is the instantaneous Voltage at 90 degrees? Answer on Volts accurate to one decimal place.
