1. What is the difference between peak-to-peak voltage and RMS voltage? 2. How should the Oscilloscope settings be adjusted when measuring AC voltages of unknown magnitude and frequency? Solution 1. With AC sine waves, the peak value is the highest point in time of the sine and the peak to peak is twice that being that the signal is symmetric around zero. RMS voltage is used to compare the power dissipation with AC and DC waveforms. If an RMS waveform of AC signal is present and is same value as the DC waveform then it is said both waveforms give same amount of power in the circuit. Also, they are related by Vpeak = VRMS x 2. 2. To determine the magnitude of an unknown alternating voltage, the main thing is to select the maximum voltage division showing the oscilloscope, and the tip of selecting the maximum impedance measurement. To determine the frequency of the signal you use the Lissajous figure, which compare the unknown frequency with a known frequency that usually comes from a signal generator..

1. 1. What is the nominal price of an orange in 25 years if the real price is $3, and the inflation rate
is 2.5%?
$3.08
$5.43
$4.56
$5.56
2. The yield on a bond is 12% and inflation is expected to be 3%. Calculate the real interest rate
on the bond.
9%
8.74%
8.04%
9.28%
3. What is the real price of an orange in 10 years if the nominal price is $1.50, and the inflation
rate is 4%?
$1.50
$2.22
$1.01
$1.41
$3.08
$5.43
$4.56
$5.56
Solution
Answer:1 Nominal Price=$3*(1.025)25=5.56
Answer:2 Calculation of the Real interest rate:
Real interest rate=[(1+interest rate)/(1+inflation rate)]-1
=[(1.12/1.03)]-1
=8.74%
Answer:3 Real price=$1.50(1.04)10
=$2.22
