How to solve circuits

how to solve circuits

1. Series circuit
2. You have to search V1, V2, V3, It and Rt 
3. To know the V1, V2 and V3 you have to apply the Ohm's law: V1=R1I1 
4. To know the It, you have to do the Ohm's law: I=V/R
5. To know the Rt, you have to do Ohm's law: R=V/I

1. Parallel circuit
2. You have to search Rt, I, I2, I3 and It
3. To know the Rt you have to do

What is a circuit?

A circuit is a closed loop that electrons can travel in. A source of electricity, such as a battery, provides electrical energy in the circuit.  Unless the circuit is complete, that is, making a full circle back to the electrical source, no electrons will move.

Circuit elements:

• Switch
• Battery
• Led
• Voltmeter and ammeter
• Resistor
• Inductor
• Motor

Series circuits:

Series circuits are sometimes called current-coupled or daisy chain-coupled. The current in a series circuit goes through every component in the circuit. Therefore, all of the components in a series connection carry the same current.

A series circuit's principal characteristic is that it has only one path in which its current can flow.

Parallel circuits:

If two or more components are connected in parallel they have the same potential difference (voltage) across their ends. The potential differences across the components are the same in magnitude, and they also have identical polarities. The same voltage is applied to all circuit components connected in parallel. The total current is the sum of the currents through the individual components, in accordance with Kirchhoff’s current law.

Mixed circuits:

A third type of circuit involves the dual use of series and parallel connections in a circuit; such circuits are referred to as compound circuits or combination circuits. The circuit depicted

Basics about electricity

Basics about electricity

• Voltage: Voltage is the number of volts that act on an appliance or on an electrical system. It is measured in volts and its symbol is V.
• Intensity: Intensity is the level of force with which a magnitude, a property, a phenomenon, etc. is expressed. It is measured in amperes and it symbol is A.
• Resistance & ohm's law: In the context of electricity, the concept refers to the component of a circuit that hinders the advance of the electric current, to the general obstacle exerted by the circuit over the passage of the current. It is measured in ohms and its symbol is omega Ω.
