Q 1) For the parallel network in Fig: a. Find the total resistance. b. What is the voltage across each branch? c. Determine the source current and the current through each branch. d. Verify that the source current equals the sum of the branch currents. RT 24 V R E 10 kfl R 1.2 kfl R, 6.8 kn

2. Calculate the time delay for a phase angle of 45° at a frequency of 500 Hz. 3. The sine wave of an alternating current shows a maximum value of 80 A. What value of DC current will produce the same heating effect?

a) calculate the resistance R12345 between points A and B when no voltage source is connected - calculate the resistance R34 between resistors R3 and R4: - calculate resistance R345 between resistors R5 and R34: calculate resistance R2345 between resistors R5 and R345 b) calculate the current IR5 through R5 so that the voltage source is connected. - calculate the current from the source:- calculate the current through the rice tower R 1:- calculate the current through the replacement resistor R2345:- calculate the voltage drop across R2:- calculates voltage drop over compensation resistance R345:-check that the resistors R2 and R345.- calculate the current through R34: c) calculate the voltage UR4 over R4 when the voltage source is connected - The resistors R3 and R4 are connected in series, ie they have the same current that passes through both resistors I34 but divides the voltage into two voltage drops UR3 and UR4.Calculate the voltage across R3:Check that resistors R3 and R4 are…
