Q4: A portion of a residential service to a home is depicted in figure
a. Determine the current through each parallel branch of the
network.
b. Calculate the current drawn from the 120-V source. Will the 20-A
circuit breaker trip?
c. What is the total resistance of the network?
d. Determine the power supplied by the 120-V source. How does it
compare to the total power of the load?
Q5:
1-Find the voltages V1 and V2 for the loaded potentiometer
2-What are the voltages V1 and V2 with no load Applied
Q6: find vrms
Q7: find vrms
Q8: When the variable load resistance RL is 1 kΩ the measured
voltage Vm is 30 volts. When RL is lowered to 10Ω the voltage drops
to 3 volts. What would you expect Vm to be when the load resistance
is removed?
