Shows how to claculates the voltages, resistances and currents for a circuit containing two parallel resistors that are in series with one other resistor. • In a series circuit, the current is only able to flow through a single path. In a series circuit, the current is the same throughout the entire circuit. The voltage in a series circuit is divided across each of the resistors. If one of the resistors in a series circuit stops working, the current will not be able to flow through the rest of the circuit. • In a parallel circuit, the electrical current flows through multiple paths before returning to the power source. The voltage drop in a parallel circuit is the same across all of the resistors. In a parallel circuit, the current is divided up through each of the resistors. If one of the resistors in a parallel circuit stops working, the other resistors in parallel will be able to continue to working. • A resistor limits the electric current that flows through a circuit. Resistance is the restriction of current. In a resistor the energy of the electrons that pass through the resistor are changed to heat and/or light. For example, in a light bulb, the tungsten filament acts as a resistor that heats up because of the current going through it, causing it to glow. Ohm’s law, V = I x R, states that the voltage drop across a resistor is equal to the product of the current flowing in the resistor multiplied by the resistance of the resistor. • You can see a listing of all my videos at my website, http://www.stepbystepscience.com • Link for sharing this video: • Resistors in Electric Circuits (9 of ... • Support my channel by doing all of the following: • (1) Subscribe, get all my physics, chemistry and math videos • (2) Give me a thumbs up for this video • (3) Leave me a positive comment • (4) Share is Caring, sharing this video with all of your friends
