Project Statement A. It is required to introduce an additional load to cause maximum power transfer from the circuit below at the terminals a and b. The parallel loads resistances already connected are 50 Ω, 40 Ω, 30 Ω, 20 Ω, 10 Ω. 10 A 30022 w 8 Ω 5.2 Ω w w a + 500 V 12 Ω B. The circuit below is connected for long time to the terminal a and b of the circuit above after witch the switch is disconnected to allow the inductance system to discharge its stored energy. Determine the discharge current each τ and for 20 t and plot the current discharge behaviour. a 7 H 100 Ω 8 H 6H 10 H b C. Modify the 100 2 resistor or the inductor setup or both resistor and inductor setup to force the discharge current to be at least three times slower than in case B during the discharge. Your report must show the design steps and calculation then the relevant plots.

A 40 - Ω resistor is connected in series to a parallel combination of a 60 - Ω resistor and a 30 - Ω resistor to form a load across a 120 – volt source. Draw the closed-circuit diagram. Determine the current through and the voltage across each resistor.

The circuit has two DC operating points. Determine both of them.

Which statement is correct about a series circuit? The sum of currents in each load multiplied by the total resistance determines t voltage. The sum of the individual resistances equals the total resistance. The sum of all the voltage drops equals the source voltage. The voltage drops are equal to the input source. In a series circuit, the current, I, is Different in each resistor The highest near the positive and negative terminals of the voltage source The same everywhere Different at all points along the circuit
