    Problem #1

     To find total RESISTANCE (Rt) in a series circuit - you simply ADD the resistances.

Rt = R1+R2+R3

Rt = 9 ohms + 3 ohms + 12 ohms = 24 ohms

                                    Note:
 

                                              To find current flow in the circuit, Ohm's Law is used:

   It = Et/Rt

It = 12 volts/ 24 ohms = 0.5 amps



        Problem #2

            To find Rt in the circuit:

Rt = R1+R2

Rt = 6 ohms + 6 ohms = 12 ohms

            To find It in the circuit:

It = Et/Rt

It = 12 volts/ 12 ohms = 1 amp


    Problem #3

        To find Rt in the circuit:

Rt = R1+R2+R3+R4

Rt = 3 ohms + 2 ohms + 6 ohms + 1 ohm = 12 ohms

            To find It in the circuit:

It = Et/Rt

It = 12 volts/ 12 ohms = 1 amp



        Problem #4

            You have to find Rt first:

Rt = R1+R2+R3

Rt = 3 ohms + 1 ohm + 2 ohms = 6 ohms

            You have to then find It using Ohm's Law:

It = Et/Rt

It = 12 volts/ 6 ohms = 2 amps

            But we know that there is only one path for current flow - therefore the
            current flow is the same at any point in the circuit:

It=I1=I2=I3....

A1=A2=A3=A4= 2 amps
