Calculation of current

(1) 10 = (100 + j11.2)I1 - j37.7I2 (2) j20 = -(200 + j11.2)I2 + j37.7I1 Please solve these two simultaneous equations to find the value of I1 and I2. Thanks

Find the diode current in the bridge circuit

Find the diode current in the bridge circuit. Assume that the diode drop is 0.7 V. See Jpeg attachment.

AC Power and transmission lines

An AC power generating station provides single phase power to a consumer 100 the generator end of the voltage at miles away, over a transmission line. The voltage at the consumer end of the line is 10KV. The consumer uses exactly 100Kwatts of poer at the distant end. If the wire in the transmission line has a resistance of 0. ...continues

operational amplifier

An operational amplifier (Op-Amp) circuit is built to measure the temperature of an exothermic process in a lab. The circuit uses a thermistor (Resistance Temperature Detector) to monitor the target temperature and a voltmeter to measure the output voltage of the Op-Amp ciruit. Since the thermistor is a passive device, it requ ...continues

LC Circuit w/ constant current source and 2 switches

Hi, I know you do not do homework assignments but I am studying for a test tomorrow and these are practice tests w/ no answers and so I really need to learn how to do them. Could you please help me understand the entire problem (again, this is not a homework problem, just practice.)?

Solve a Quadratic equation with complex numbers

PLEASE SEE ATTACHED (Four possible answers are shown in the attachment) Solve the equation Z2 +Z+1=0 using Z=(X,Y)

LET Z1 = (-1,-1) AND Z2= (1,1)
