Intuitive way to think of transistor saturation current?
2 votes

This is more of an intuitive answer rather than a very technical one. Let's look at the following circuit. In layman's terms, here a power source of 5V(connected at the top) is trying to establish a ...

General approach to solving base resistor for a CE amplifier circuit that has no voltage divider at the base
2 votes

Start with applying Kirchhoff's voltage law on the path shown: In this loop only base current is unknown. Find it. Next, apply kirchhoff's voltage law in this loop: Use, Emitter Current=Collector ...

Will a capacitor draw charge/current if it's not feeding a load?
1 votes

Theoretically, zero current will flow when the switch is open. This is because once the capacitors fully charges up, they will not conduct any further. Or you can say, Capacitor blocks DC. Practically,...

Why does current not increase when batteries are connected in parallel?
1 votes

The real workhorse behind the current is voltage. More the voltage for a fixed resistance, more will be the current. In your first case the series equivalent voltage is 3+3=6V. In second case, ...

Confused about op amp equation derivation
0 votes

The term that you are asking for, is the gain of the OpAmp when the input is applied to the non inverting terminal (given there is ground instead of Vin in your circuit). The voltage at the non ...

How to identify branches of root locus from figure/plot?
0 votes

A branch in a root locus starts from a pole and ends on a zero. These zeroes and poles may also be at infinity so you may have branches coming from, or going towards infinity. But it is easy to see ...

I'm working with 12V 6.5A power supply, should I be worried?
0 votes

I want to put a point here: 'It's not the Voltage but Current that kills someone " The current rating of your power supply is not what it will always deliver. This rating simply indicates that this ...

Is it possible to connect one electrical device to two electric sockets?
0 votes

If you are doing this with sockets connected to the same power lines and you connect live to live and neutral to neutral then it is nothing which can theoretically misbehave. But if you flipped the ...
