Perform many calculations and show the formulas used for each step.

My school required me to pick a class outside of my field of study in Information Security and halfway through, I realize I mad a poor choice. The first half of the class was Ohms Law and a few other simple formulas and wasn’t that bad. See attached for full problem description.

LCR Circuits: Phase difference between voltage and current.

Given that R=1 kilo ohm, C= 1micro farad and L= 100 milli Henry’s calculate the frequency at which the current in an LCR series circuit lags the supply voltage by 45 degrees.

Calculating current, impedance and voltage in a circuit in polar form

Full question attached as a file Calculate values of I1, I2, I3, V1, Vs and total impedance in circuit shown, giving answers in polar form using V2 as the reference. I have calculated the following and think they are correct: I1=1.01 I2=1 I3=1.43 V1=2.02 Vs=2.93 I am lost with the polar form using V2 as a referen ...continues

Power factor in AC circuit

A single phase electric motor has an output power of 10 kW and an efficiency of 90% at full load. The motor is fed from a 240 V supply via a cable that has a resistance of 10 milli ohms per metre length. If the terminal voltage to the motor must not fall below 90% of the supply voltage, calculate the maximum return length of the ...continues
