Will the current in a light bulb connected to a 200-v source be greater or less than when the same bulb is connected to a 110-v circuit?

It will be greater:
current = voltage / resistance
Since the bulb's resistance doesn't change, then current is a direct function of voltage.

How much current will flow in a circuit with a 12 VDC source connected to a 1K-ohm load?
I = E/R = 12/1,000 = 0.012 ampere = 12 milliamperes.
Why does a circuit stop working when you remove the battery?
The battery is the power source of the circuit. It supplies current to the circuit and the circuit is simply a path for the current to follow. When you remove the current (battery), the path still exists but there is no current going through it.
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source. What is the current running through the entire circuit?
6
What does series mean in series circuit?
In a series circuit, the loads are connect much like the cars of a train, with the output of one device - a resistor, for example - connected to the input of another. With the source and all loads connected, the components will be connected together much like the links of a bracelet, with no alternate paths for current flow. If one load device becomes open, then all devices will be de-energized. This is opposed to a purely parallel circuit, where all of the load device inputs are connected to one side of the source, and all of the load device outputs are connected to the other side of the source. This provides a separate path of current flow for each load device. Should one or more load devices become open, the remaining devices will continue to function, due to the alternate current paths. In series-parallel circuits, there is a combination of both types within the same circuit. Any combination of series and parallel paths can exist within the circuit.
How can you find the steady state current in RLC series circuit?
-- If the excitation source is AC, then the steady state of the circuit depends on the voltage, frequency, and waveform (harmonic content) of the source. -- If the excitation source is DC, then the steady state current in a series circuit is zero. DC doesn't pass through a capacitor.
What is required for current to flow through an electrical current?
Potential Source connected across a Closed Circuit Path.
How do you read a circuit diagram?
Start dictating form the source current thor' the Load connected.
How will the values of the current obtained vary if the second source is connected in the middle section of the circuit instead?
thanks for the answer
What determines the actual magnitude and direction of current through voltage source?
The voltage itself will determine the direction of current (assuming there isn't another source pushing current through the source backwards); the amount of current will be determined by the thevenin equivalent resistance of the circuit connected to that source (the resistance "seen" by the source, which can be lumped into a single circuit element).
What is a circuit which will allow flowing current?
As long as an electrical power source is connected to itself with electrical conductors of some kind, then a current will flow through it. How much current will depend on the components used in the circuit.
How does a inductor or capacitor returns power to circuit?
A: Current flow only if there is a return path to the source it does not matter what it is connected to. What leaves at one end of the source will be identical to the return in current
What are sreries circuits?
An arrangement circuit is a circuit where there is one and only way from the source through the greater part of the heaps and back to the source. This implies the majority of the current in the circuit must move through the greater part of the heaps. One illustration of an arrangement circuit is a string of old Christmas lights.
Wt is source current and sink current in a DC regulator?
The source current is that current which will leave the DC regulator and travel to the load circuit connected to it. The sink current is that current which may come from the load circuit and attempt to find a path through the ground through the regulator. Generally most regulators are designed to just source current to a load and are not setup to receive current back(sink it)
When the transformer is connected to the power source the secondary current is 0 what is the possible fault in the transformer?
A secondary current of 0 would suggest to me that the secondary circuit is open. A normally operating circuit with zero current flow would be very unusual. No load in secondary circuit. No secondary current can also be attributed to the primary power source open or an open primary winding.
Why current source is replaced by open circuit across the terminals?
For an ideal current source, this means replace the current source with an open circuit. Resistance can then be calculated across the terminals.
What is the flow of an electrical current in a circuit outside the power source?
Usually a circuit is connected to a power source, which could be a battery or an outlet. When this happens current flows through the circuit. The power supply raises electrical charges through the required potential difference, and then in the circuit the charges flow down the potential gradient giving up their energy.
Why does a bulb in a circuit not work?
A light bulb is not lit when the swtich is not connected to the wire becasue there is no flow of electricity, specifically, flow of electrons. By disconnecting the wire, the bulb is no longer connected to the electricity source.
