[LAB 2] For the circuit in Figure 12 in the lab manual. What is the size of the resisitor that will result in current I = 2A?
4 ohms
[LAB 6] _________ is a device that stores electrical energy by means of an electrical field, which is created by electrically charged particles
A capacitor
[LAB 5] What is the difference between AC and DC coupling?
AC coupling only shows the AC component of the signal whereas DC coupling shows both AC and DC components
[LAB 1] What can you deduce from the measurement of I1 and I2?
I1 = I2
[LAB 3] For circuit 2 and the subsequent circuits, what is the relationship between 𝐼1,𝐼2 and I3?
I1 = I2 + I3
[LAB 1] Put R3 back in the circuit. Write KCL at node D.
I2 = I3 + I4
[LAB 6] __________is a device that stores electrical energy by means of a magnetic field, which is created by charged particles that are in motion
Inductor
[LAB 3] In the lab question at the end, what is your result for K1 and K2?
K1 = R2*R3/(R1*R2+R2*R3+R1*R3) K2 = R2*R1/(R1*R2+R2*R3+R1*R3)
[LAB 2] In circuit 6, if we change the resistor such that the voltage drop across it is higher than 3V. What happens to the LED? Assume LED lights up at 1.7V
LED turns off
[LAB 6] If we didn't include the internal resistance in the calculation, do you think that it'g gonna make a big difference in the results?
No, because we have a 1 kOhm resistor in the circuit which is much bigger than the internal resistances of the components.
[LAB 1] Write KVL around the larger loop
Vab + Vbc + Vcd + Vda = 0
[LAB 3] Based on your answer to the previous, which power supply has a bigger effect on the output voltage?
Vin2
[LAB 1] How does the current change in the whole circuit?
decrease
[LAB 1] If voltage is taken going from A to B, is this a potential gain or loss across the battery?
gain
[LAB 1] Remove R3 from the circuit and note the voltage drops between node C and D, and D and A. Does the resistance of the whole circuit increase or decrease?
increase
[LAB 5] Why does the probe display a signal whenever its tip is tapped by your finger?
it reads the electrical signals from the heart
[LAB 7] For circuit 1: what type of filter is it?
low-pass filter
[LAB 7] For circuit 2: what type of filter is it?
low-pass filter
[LAB 5] Based on the result of step 5, what conclusion can you draw regarding how internal resistance changes with resistance of the circuit?
mostly consistant
[LAB 4] For the circuit in Figure 8 in the lab manual. What will happen to Vth and Rth in case a (use superposition to find the contribution of each source to Vth)
no change in both
[LAB 4] For the circuit in Figure 9 in the lab manual. What will happen to Vth and Rth in case b (use superposition to find the contribution of each source to Vth)
no change in both
[LAB 6] The unit for RC is seconds and the unit for L/R is also seconds. What will the appropriate units be for LC?
s^2
[LAB 5] Explain the purpose of the triggering function.
the triggering function allows manipulation of the time varying signals, allowing for a stationary image to be 'caught' and analyzed.
[LAB 1] Does that verify KCL at node D?
yes
[LAB 1] Does that verify KVL around the large loop?
yes
[LAB 1] Should I3 and I4 be of the same value?
yes
[LAB 1] Substitute your measurements in your choice above, are the two sides equal?(They may not be exactly equal, but very close, wink wink)
yes
[LAB 1] substitute your measurements in your choice above, are the two sides equal?(They may not be exactly equal, but very close)
yes
[LAB 2] Do the characteristic curves of each non linear component agree with the theoritcal behaviout predicted?
yes
[LAB 3] Based on your answer to the previous questions, does that verify the superposition principle?
yes
[LAB 4] Based on your answer to the previous question, does that verify Thevenin Equivalence?
yes
[LAB 4] Does the voltage you measured in Q7 matches what you measured in Part A Q3?(little difference is acceptable)
yes
[LAB 3] For circuit 2 and the subsequent circuits, what is the relationship between 𝑉(𝑜𝑢𝑡)1, 𝑉(𝑜𝑢𝑡)2 and 𝑉(𝑜𝑢𝑡)total?
𝑉(𝑜𝑢𝑡)total = 𝑉(𝑜𝑢𝑡)1 + 𝑉(𝑜𝑢𝑡)2
