Assuming that the voltage between two nodes are the same, current changes with branches. If you add branches, this means the current will be divided, depending on the resistance strength. Greater the resistance, the lower the current. If there is no resistance, it will end up in a short circuit, getting all the current. If there is great resistance, there will be very little current passing.
Mathematically, V=I*R is the formula. If you know the voltage between two nodes, you can calculate the currency (I) in each branch and for the whole nodes by putting in the particular resistance value for the branch or the whole nodes.

What happen if you change the position of ammeter in the circuit in parallel and series?
-- In a series circuit, no matter where you install the ammeter, it will always read the same current. -- In a parallel circuit, the ammeter may read a different current when it's moved to a different parallel branch.
How are current and voltage related to the power supplied by the source?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
How do currents flow round two series and parallel circuits?
In a series circuit, the current does not change. It is simple the total voltage divided by the total impedence. However, in a parallel circuit the current splits. More current will go down the path with less impedence, and vice versa. For example, you have two parallel branches, 1 and 2, with resistances R1 and R2 respectively. Also, the total current flowing is I, while the current down each branch is I1 and I2. I1= I(R2)/(R1+R2) I2= I(R1)/(R1+R2) Also note that I1 + I2 = I.
In the parallel circuit what characteristic was the same throughout the experiment?
In a parallel circuit, the voltage across all components remains constant and is the same throughout the experiment. This means that each component experiences the same voltage, regardless of the individual current flowing through them. As a result, while the total current in the circuit may vary, the voltage across each branch does not change.
WHY does adding more loads in a parallel circuit increase the current?
Adding more loads in a parallel circuit increases the current because of Kirchoff's voltage and current laws, and because of Ohm's law...1. Kirchoff's voltage law states that the signed sum of the voltage drops around a series circuit is zero. A consequence of this is that the voltages across elements of a parallel circuit must be the same.2. Ohm's law states that current is voltage divided by resistance. Since the voltage across each new parallel element is the same, the current in that element is known. A consequence of this is that each additional element does not change the current in the other elements.3. Kirchoff's current law states that the signed sum of the currents entering a node is zero. A consequence of this, and 1 and 2 above, is that the currents added by each parallel element increases the total current entering the set of parallel elements.
Why parallel circuit is known as current magnification though it has minimum current at the time of resonance?
In a parallel circuit, each branch has its own current path, allowing the total current to be the sum of the currents in each branch. This is why it is known as current magnification. However, at resonance, the impedance in the circuit is at its minimum, causing the total current in the circuit to decrease. This does not change the fact that individual branches can still have higher currents than in a series circuit due to the unique current paths in a parallel arrangement.
What happen if you change the position of ammeter in the circuit in parallel and series?
-- In a series circuit, no matter where you install the ammeter, it will always read the same current. -- In a parallel circuit, the ammeter may read a different current when it's moved to a different parallel branch.
Meaning or definition of voltage in a parallel circuit?
Voltage is the electrical potential that is produced by a given source (ie, a battery or a generator). The voltage is not changed by the type or number of loads on a circuit. A voltage regulator and/or transformer may change the voltage within a perticular load, but cannot change the complete circuit voltage.
What would happen if a lamp was unscrewed from a parallel circuit?
There will be no change, because it is a parallel circuit.

Also, the total current flowing is I, while the current down each branch is I1 and I2. I1= I(R2)/(R1+R2) I2= I(R1)/(R1+R2) Also note that I1 + I2 = I.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
How does the behavior of a circuit change when a capacitor and resistor are connected in parallel?
When a capacitor and resistor are connected in parallel in a circuit, the behavior changes in that the capacitor stores and releases electrical energy while the resistor controls the flow of current. This combination can affect the overall impedance and time constant of the circuit, leading to changes in the voltage and current characteristics.
What will happen if you change polarity in parallel circuit?
If you reverse the polarity in a parallel circuit, the components will still function but the direction of current flow through each component will be reversed. This could lead to a change in the behavior of any polarized components in the circuit, such as diodes or electrolytic capacitors. It is important to ensure that the components can handle the reversed polarity to prevent damage.
In series circuit is currant change with change in resistance?
V=IR where V is voltage, I is current and R is resistance. You want to know what the current will be in a series circuit based on the resistance. You need to know the voltage as well as the resistance, gives you the equation as follows I=V/R So if you have 10 volts and a 1 ohm resistor, the current will be 10 amps. If you increase the resistor to 10 ohms, your current will then be 1 amp. In a parallel circuit, the resistance is equal to the sum of the inverse. For example. If I have two resistors of 2 ohms each in parallel, the equation would be 1/2 + 1/2 = 0.5 + 0.5 = 1 In that particular instance, your current would increase.
In the parallel circuit what characteristic was the same throughout the experiment?
In a parallel circuit, the voltage across all components remains constant and is the same throughout the experiment. This means that each component experiences the same voltage, regardless of the individual current flowing through them. As a result, while the total current in the circuit may vary, the voltage across each branch does not change.
Why does parallel circuit have higher current than the series?
Parallel branches each draw a current from the supply. The more branches, the more current is drawn. Adding additional loads to a series circuit increases its resistance, causing its supply current to reduce.
