Hello all I have been attempting a repair on a Archt one speaker for about a month now and I just can’t figure it out. I’ve probed around, I’ve tested the speakers in a home theater just to make sure they work and they do just fine, but when put together I get no sound through BT or through Aux...
I would like to fully charge then discharge the capacitor using the two switches . Charge for 50s then discharge for another 50s seconds. Please help me. I am not getting the capacitor to discharge pass half the source voltage.
Hi all i have a problem with a LM741 op-amp,
when calculating the output voltage i should have when inputting 12vpp using the formula Vo = Vi(1+Rf/Ri) and the values being vi = 12 rf = 6k Ri = 1.5k i should be having an output of 60v, but when building and simulating my design i only have...
Hello, I can't find anything about what capacitor to supply to a circuit. And why to supply it to a circuit. If I e.g have a circuit with a battery and a led, the battey is 3.2v, and the led's forward voltage is 2v, and the current limit is 20mA to the led.
Oh, and what happens when a capacitor...
Hello, I have a power supply that goes in the wall charger from 220v AC or something to 12v 2.5A DC, but I want to decrease the 12v 2.5A DC to 12v 1A DC...
Can someone help me to tell how I get 12v 2.5A to 12v 1A?
Best regards Adam.
