## parallel circuit## Resistance in a parallel circuitThe total resistanceR of two conductors of resistances _{T}R_{1} and R_{2} connected in parallel is given by:
1/ ## Voltage in a parallel circuitComponents are connected across the same voltage source, and therefore the voltage across each of the components is the same. This fact can be expressed mathematically asV = _{T}V_{1} = V_{2}, where V_{T} is the total voltage, V_{1} is the voltage across component 1, and V_{2} is the voltage across component 2. Appliances are connected in parallel
circuits with the same voltage applied to each appliance. ## Current in a parallel circuitThe current divides to flow through each of the components in the parallel paths. The amount of current that flows through each of the components depends on the resistance of each component. A component with a lower resistance will allow more current to flow through. IfI_{1} is the
current flowing through component 1 and I_{2} is the current
flowing through component 2, then the total current, I,
is given by _{T}I = _{T}I_{1} + I_{2}. See also series circuit. ## Related category• ELECTRICITY AND MAGNETISM | ||||||
