    How do you connect all the voltages together into one?

    Hi Steve, wouldn't having an extra 5v output at a darlington pair be a separate source as the original voltage supply is 9v? I'm quite sure my lecture teacher had said something about it when I was still studying. What I can remember is that the 5v can be added onto the 9v as one output...

    How do you connect all the voltages together into one?

    Hi, I am currently studying how to add all the voltages together at the end of a circuit. For instance, i have a 9V power supply that's going into the entire circuit and have gathered 5V from the Darlington Pair, 5V from the op amp and an extra 6V from the capacitors. The problem i am having...

    Temperature In Household Electrical Line

    Hi, I was just thinking the other day about what the temperature is of the household electrical line. I tried looking it up on google but no one seems to have posted anything about it so i would just like to know how much temperature does the electrical line have in the average household? You...

    Can AC/DC be placed into a D Flip Flop?

    ok that's fine. Thanks for the answers.

    Can AC/DC be placed into a D Flip Flop?

    Hi, I was just experimenting whether AC/DC can be placed into a D Flip Flop? I was thinking that since AC is not direct can this be possible for the D flip flop to move from D Flip Flop 1 to D Flip Flop 2 and vice versa?

    555 IC not amplifying enough

    HI sorry for the delay. Ok so what i am trying to do is break a wine glass using an oscillator and capacitor charge/discharge circuit but I found that an op amp was better. This should be achievable with just an oscillator and op amp. I managed to fix the oscillator's output to produce...

    555 IC not amplifying enough

    the 555 starts to charge up again and is ready for the next time interval. i looked at the op amp 741 and it seems to boost it a little which is quite disappointing as i attached the 555 output to an inverting DC amplfier, I thought it would amplify the output but it only reduced it.

    555 IC not amplifying enough

    Well i looked at some tutorial graphs and it showed that the higher the voltage level the more amplified it is not causing the freq to change. So i wanted to see if i could do it but i have had no luck so far. However it is also possible to change the duty cycle (which is why i have the 100K...

    555 IC not amplifying enough

    Hi, I am doing a combined circuit involving a 9v battery, a 555 IC oscillator (with timing input of 1K + 1 nF cap, 100K pot for pulse width modulation) and a charging / discharging circuit using a 2200 uF 25V cap with a 10 ohm resistor for charging and a 100 ohm for discharging. When i...

    Formulas for Voltage, Current and Resistors

    Hi, Its been a long while i've been on here since i was busy with my projects. However, I'm trying to understand this idea where the current input (I) is different to the voltage input (V). Because my multimeter is damaged from when i opened it up to repair it, i am pretty much using I = V /...

    Increasing Current

    Its ok, i've found what i was looking for. Btw, thanks for the study tip Davenn, i don't mind reading up on it some more. :) This thread can be closed now.

    Increasing Current

    That is not true. Each separate individual line is constantly flowing the same electricity through it therefore it is quite possible to achieve an increase in current by placing each separate individual line in parallel, having the total through a single output. At least that is the idea. I...

    Increasing Current

    Sorry my fault Adam, i didn't break the circuit and inserted the black and red probes so the current couldn't be read through the multimeter.

    Increasing Current

    I am using a multimeter to measure it. The red probe is in the 10A slot, the black probe in the COM and the switch is placed on 10 A current.

    Increasing Current

    Hi, I'm needing help in increasing current from a 1.5 V batt by placing down 3x 100 ohm resistors in parallel circuit with an output. However, i have encountered a problem and found that the resistors (even though they each have their own line) tend to give out about 0.3 A of current each but...

    How do I increase energy flowing into a Capacitor?

    Sorry for the delay but yes that is true and correct. I was studying how to increase current and found out that i just needed a pos (+) and neg (-) as well as to find a track opening somewhere on the circuit. So this is what i did: I got the same current output as what was coming into the...

    How do I increase energy flowing into a Capacitor?

    My second point is at the 1.5V batt pos (+) ok, i have attached the circuit diagram (as well as an alternate design) but i am still thinking about whether i should keep the first cap (80 uF 330 WV) The 1st design The Alternate The value of the original capacitor is 80 uF 330 WV and...
