### Ohm's law of a circuit which has both a voltage source and current source

The voltage source has a specific voltage through it regardless of the circuit's current and its resistance while the current source has a specific current through it regardless of the voltage through ...

### Paralleling power supplies for higher current

I am looking at using two Cincon (CFM80S240 and CFM60S240) power supplies in parallel to achieve a higher current output. Is this possible? If so, can I just hook them up in parallel, or is there some ...

### How is a current controlled voltage source different from a resistor?

A current controlled voltage source produces a voltage that is linearly proportional to a current. A resistor has the same behavior. And the gain for a CCVS is measured in ohms, which is the same ...

### Voltage sources in parallel [duplicate]

If we attach two voltage source of same value than what happens? I mean what's the difference between using a single voltage source and two same valued voltage sources in parallel? As they both supply ...

### Explain in layman's terms Vgs and Vgs(th) of MOSFET's

I'm trying to understand $V_{GS}$ of MOSFET transistor. From what I understand $V_{GS}$ normally stands for voltage gate to source breakdown, but other than that I lack an understanding. \\$V_{GS(...

### How to improve load transient response of an LM317 voltage-regulator powering an audio amplifier?

I am building a voltage regulator circuit for powering a pair of mini-speakers (about 3-5W) with built in amplifier and an old mp3-player/FM radio. The power source is an old mobile phone charger (...

### What should I use from given options to power a raspberry pi?

I have a system which consists of 2 12V DC motors(0.65 A on max load) and 1 RPi 2 model B. I want this system to be plug free. I have Li-Ion batteries to power up motors. I use a L298N module to drive ...

### why does the parallel resistors with voltage source can be ignored as well as resistors in series with current source in term of equivalent circuit?

I have a problem dealing with equivalent circuit. I don't know why when the resistors that is parallel with the voltage source can be ignore as well as one in series with current source. Of course the ...
