No it depends on voltage and circuit resistance and other physical parameter which affect the properties of component used in circuitry like -
temperature
pressure
humidity
light(in light sensitive circuit- LDR photo diode,photo transistor,)
and other.

What happens to the voltage in a series circuit when more loads are added?
A: assuming a infinite current source the current will increase accordingly
Is voltage and current proportional to each other?
Yes, in accordance with Ohms law. Accross a given resistance, current will increase directly proportional to the increase in Voltage. Voltage(Volts) = Current (in Amps)x Resistance(in Ohms) You can transpose the formula to find the unknown, given 2 of the values.
Why 250 volts AC in New Zealand instead of 110 volts AC which America uses is one safer and is more energy footprint required to produce the higher voltage?
The reason for increasing the voltage in the electric network is, in fact, that it saves energy. The power dissipated in electric wiring is proportional to the square of the electric current. By increasing the voltage, the current decreases provided that the power consumption at the consumer is to remain constant. This means less loss in the electric network. For the same reason, very high voltages, hundreds of thousand volts, are used in long-distance wires. The voltage is converted using transformers when it reaches the consumers, with a relatively low power loss.
If the resistance in the circuit is increased what will happen to the current and voltage?
* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.
What is the name of conductor which obeys ohm's law?
Everything obeys Ohm's law - antennas, cables, transformers, integrated circuits, etc.AnswerIt is not true that 'everything' obeys Ohm's Law. For a device to obey Ohm's Law, the ratio of voltage to current MUST remain constant for variations in voltage. This is why Ohm's Law is a law of constant proportionality.
How can in series connection current remain constant while the voltage change while by ohm's law voltage is directly proportional to current?
If the voltage between the ends of a series circuit changes, the current in thecircuit definitely does not remain constant. The current does change by the samefactor as the voltage.The current at every point in the series circuit is the same current.
How long does current remain in a 220 volt circuit?
The current will remain in a 220 volt circuit as long as the circuit load remains in the circuit and the circuit remains closed.
When current remains constant and resistance increases the voltage in the circuit will?
The physical equation governing voltage is V = IR, where V is voltage, I is current, and R is resistance. If V remains constant while R is increased, I or current must decrease. Increasing the resistance in a circuit is simply introducing a material that further resists or impedes the electron flow (current), thus current decreases.
What happens when you halve the resistance in a circuit when voltage remain constant?
Since resistance is the ratio of voltage to current, we can say that halving the resistance will result in twice the current.
What happens to the voltage if the current increases?
Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.
What happens to the current flow in a circuit when a second component is added in series?
The total current decreases.According to the Ohm's law the current & the resistance are inversely proportional so when we put a load in series with the existing load, the resistance of the circuit increases therefor the current decreases.
What happens to the voltage in a series circuit when more loads are added?
A: assuming a infinite current source the current will increase accordingly
What happens to the power in a circuit as the current increases?
P=VI If current (I) increases then P will increase proportionally. That is, assuming that voltage (V) remains constant. If voltage decreases and current increases or vice versa, proportionally then P will remain the same.
In series circuit why current drop beceause according to kichroff law cuurent remain same in series circuit?
In a series circuit current does stay the same thoughout the circuit, voltage drops in the series circuit.
How an electric current is produced?
When charges (means charged bodies) move , then we say that an electric current is produced. If charges remain at rest, current is zero. If charge Q moves through a metal in time t , then current I through metal is: I=Q/t; moreever, electric current can also be produced by rate of change of magnetic field through a metal...,
What remains constant in series circuit?
A: No matter how many resistor of different value are inserted the current will remain the same for each. The voltage drop will vary with the difference in resistors and i a parallel path is found along the way the current will divide according to the resistors values
In a series circuit what happens to the current if you increase the number of components in the circuit?
The current (amps) will remain constant, but the voltage will drop.
