please help me ..
*Who knows the formulas of parallel circuit?
*How to get the Current?
*How to get the resistance?
*How to get the Voltage?

Ohm's Law (V=I*R). This formula is used to solve for any unknown value of Voltage (V), Current (I), or Resistance (R), given two known values.

To calculate Voltage. Given Total Current and Total Resistance, simply substitute the values of Current and Resistance for It and Rt. In a parallel circuit, the voltage, V, is the same across all resistors. The formula is V=It*Rt To calculate the total resistance (Rt). This is done by using one of the following formulas:

1. Product over sum method Rt= R1*R2/(R1+R2) 2. Like resistor method Rt= R/n 3. Reciprocal method Rt= 1/(1/R1 +1/R2 + 1/R3)

To calculate Current. Given Voltage and Total Resistance, simply substitute the values of Voltage and Resistance for V and R; It=V/Rt. Alternatively, you could solve current of an individual resistor in a parallel circuit if necessary. When you find yourself without a calculator handy, sometimes it's easier to determine the Current of each resistor, sum them to get It, and then use that to determine Rt. To calculate the individual current for a resistor. You could use Kirchoff's current divider rule I1=IT*R2/(R1+R2), but that's more math than is necessary. It's much simpler to use the voltage applied to the resistor and the value of the resistor in question, such as I1=V/R1. Finding Power. To determine the power consumed by a circuit (or an individual resistor within that circuit), determine I and V from the above formulas, then power is expressed as P=I*V

ahh this takes me back to technical college when i took that begginer class
