    Voltage Division and Finding a Current

    No current does NOT SPLIT . Current JUST flows. The terms you use are VITAL to what you are actually saying when you are talking about electronics. SPLIT implies reduction of the source, this simply does not happen, when you branch off you are adding another current path, thus creating...

    Voltage Division and Finding a Current

    While you properly quote Kirchoffs law you are misusing the terms around it . a circuit does not divide it branches, hence the term NETWORK. the sum of all current equals the total current, this is correct, HOWEVER, this does not mean current is being divided, When something is divided it is...

    Voltage Division and Finding a Current

    JimB I suggest you educate yourself and rather quickly. I don't know what program you are using but it isn't using the circuit supplied because the circuit is incomplete, so it is you that is open to ridicule Next you can not have a current source without a voltage source. this is a simple...

    can anyone help what voltage poly cap do i need

    A common design adage when it comes to caps is the almost universal "rule of three" it falls in in first aid ( three minutes with out breathing and so on) three miles before having to stop for the wife to pee, three hours and the move is too long... one of those odd truisms of life. so...

    Voltage Division and Finding a Current

    Current never "splits" it branches. you always have to apply Ohms law. ALWAYS. when you have an equal voltage across two parallel resistors you calculate current by VOLTAGE DIVIDED BY RESISTANCE, AND THEN ADD THE CURRENT VALUES TOGETHER (caps to differentiate from the rest of the text...

    Voltage Division and Finding a Current

    You are WAY overthinking this LOOK at the circuit, trace all current paths. First rule you need to remember: Vs is NEVER in parallel with the circuit it supplies (study up on the terms source and sink for more information on this) A voltage source can ONLY be in parallel with another voltage...

    Voltage Division and Finding a Current

    No you have 2 12 ohm resistors in parallel which give a total resistance of 6 ohms. You must be VERY CAREFUL how you word things when describing circuits. for example 2 6ohm resistors in parallel will give you a resistance of three ohms a substantial error. This isn't nitpicking about...

    Voltage Division and Finding a Current

    Current is not divided in resistor circuits. OHMS LAW... you may have branch current but total current is ALWAYS based on the total resistance of the circuit. As the first circuit ONLY has a total of 9 ohms the current is Vo/9 (parallel resistance law of note in this instance is resistors...

    Voltage Division and Finding a Current

    there is no Vout , the circuit is incomplete and there is no voltage in this branch.

    Voltage Division and Finding a Current

    for your voltage divider problem a small amount of math savvy is required but not much. Each branch of the divider is done the same way so it is relatively easy. The resistor relationship is always 2/1 in this circuit. so the voltage being tapped is 1/3 of the total branch voltage. Since you...

    Voltage Division and Finding a Current

    For Problem 1 the answer for Vout is 0 (zero) volts. CAREFULLY EXAMINE the circuit. the branch circuit where you are calculating Vout is incomplete. As there is no V+ there is no Vout.... the circuit is incomplete
