Objectives: ·Using Multisim, design half wave rectifier circuits and simulate the response. ·Convert circuit voltages from rms to average values. ·Use the converted values to determine the power dissipated across the load. Results: From the half wave circuits illustrated in observation A, the average value is measured using the meter in the DC setting. The average DC voltage is the average voltage measured across the fluctuating DC voltage. In observation A, the calculation is the voltage peak divided by pi, the sinusoidal wave is half, therefore division by pi. From observation B, the meter is reading the square root difference of rms and the DC value. In a 50 percent duty cycle, the read voltage would equal half the VPP, only if the negate and positive voltages were equal. From observations C, the meter is reading the RMS power dissipated on the load resistor. The calculated average power is the DC equivalent. Conclusions: In conclusion, the rms voltage measured using an AC meter is the product of the peak voltage and the square root of 2. In a half cycle the multiple will be half of the square root of 2. For 50 percent duty cycle square waves, the average voltage is the peak voltage. On Rectangular waves, the measured average voltage is the difference of the rms and DC values. The power dissipated on the load resistor is the quotient of the rms voltage squared and the load resistor.
