This is because there is continuity in the charge flowing. There is no accumulation of charge anywhere in the circuit. Hence, since, the electric charge flowing in the series circuit has to remain constant, the electric charge flowing per second in the circuit also has to remain constant.
In series combination of resistors the current is the same in every part of the circuit or the same current through each resistor and in parallel combination the voltage remains constant.
The total resistance in a parallel circuit is less than the smallest of the individual resistances. Each resistor in parallel has the same voltage of the source applied to it (voltage is constant in a parallel circuit).
In parallel circuits, voltage is constant throughout, current depends on each resistor and the inverse of the total resistance is the sum of the inverse of each individual resistor.
In series combination the current flowing through the circuit is constant.
Current remains constant in series connection and voltage remains constant in parallel connection , current is like water flowing in rivers it always flow in specific path and with constant amount but when some diversion is created it distribute and amount decrease gradually same here with current.
Is voltage always constant? In general no, at any given time at any particular point in a circuit the voltage may vary. Some of the points in a circuit will be ground, always defined to be at zero volts, or a power supply rail, usually labeled at a fixed DC voltage.
Where A = effective plate area, d = space between plates, and ε = dielectric constant. When the connection of two capacitors takes place in parallel, then the voltage (V) across each capacitor would be the same i.e. (Veq = Va = Vb) and the division of current ( ieq ) takes place into two parts ia and ib.
Once the charges get out of the resistors, the electric field of the battery is enough to drive them mad (as the wire has relatively lower resistance). And, the charges get back their energy once again. This is the reason why we say voltage is the same in parallel circuits3.
A constant current load is one which varies its internal resistance to achieve a constant current regardless of the voltage which is being fed to it and therefore the power will vary. As the input voltage varies from 20 to 24 volts, the output might only change by a small %.
The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances.
A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in “x + 5 = 9”, 5 and 9 are constants.
Since the light can maintain a consistent brightness, constant current is typically used for signs, back-lighting, and commercial LED displays. As the name implies, only constant current LEDs are compatible with these types of drivers.
In a series circuit the current is the same at any particular point on the circuit. The voltage in a series circuit, however, does not remain constant. 4. The voltage drops across each resistor.
Capacitors in Series Summary Two or more capacitors in series will always have equal amounts of coulomb charge across their plates. As the charge, ( Q ) is equal and constant, the voltage drop across the capacitor is determined by the value of the capacitor only as V = Q ÷ C.
Capacitors in Parallel. (Conductors are equipotentials, and so the voltage across the capacitors is the same as that across the voltage source.) Thus the capacitors have the same charges on them as they would have if connected individually to the voltage source.
