Electrical Parallel Circuit

Calculate parallel resistance

1 / Total resistance = 1 / R1 + 1 / R2

• Upon finding total resistance, the total current can be determined by using Ohm's Law and the given EMF of the circuit.

• The summation current flowing through R1 and that of R2 will be equal to the total current in circuit. Current flowing into a point equal to current flowing out of a point.

• the potential difference across R1 is equal R2 and equal to that of the EMF based in the fact that parallel voltages are equal.

General Rules for both Series and Parallel Circuits

• The amount of current exit from positive terminal is equal to the amount of current entering the negative terminal of the battery.
• The amount of current in the circuit is depends on the overall resistance of the circuit.
• Voltmeter must always be connected in parallel and Ammeter in series with the circuit.
