Term
|
Definition
| current in a circuit is directly proportional to the voltage applied to the circuit and is inversely proportional to the resistance of the circuit |
|
|
Term
| list five rules that apply to series circuits |
|
Definition
| Total resistance (R) is the sum of the individual resistance. There for the Voltage at the source (Vt) is equal to the sum of the voltages at the resistance. A break anywhere in the circuit stops the electron flow in the entire circuit. Ohm's law applies to any part of the entire circuit. The current (amperage) of a series circuit is the same throughout |
|
|
Term
| List five rules that apply to parallel circuits. |
|
Definition
| A break or opening in any branch of the parallel circuit does not stop the flow of electrons to the remaining branches. The voltages across all the branches of the parallel circuit are the same, and are equal to the voltage at the source. Ohm's Law applies equally well to the total circuit or any of the loops or branches. The total current (I) is equal tot he sum of the currents flowing through each of the branches. The total resistance of the reciprocal of the sum of the reciprocals of the separate resistance in parallel |
