State three things which can affect the voltage in a circuit?
Ohms Law says that Voltage = Current * Ohms, so the twothings that can affect the voltage in a circuit are Current and Ohms. If have a non resistive impedance, i.e. a capacitor or inductor forming a reactance, then frequency can also affect the voltage but, mathematicaly, reactance is a frequency domain form of impedance, so my answer stands - Current and Ohms.
Can a digital circuit produce the same output voltage for different input voltage values explain?
No, value of output voltage depends upon the value of input voltage and digital can not produce the same output voltage for different input values. For example, suppose in a digital circuit two switches are connected. A closed switch is represented by 1 and an open one by 0. If there are two switches and we say that they are in state 1, then it would mean that both of them are closed. In this circuit after connection with the battery some current would pass so we call this current as output.Depending upon the states of the switches, the current either would pass or it would not pass.In case the current is passing, we can say the value of output is 1 and it is 0 when no current is passing. Whether the value of the output would be 1 or 0, it depends upon the values of input variables( 1 and 0) which specify the state of the switches.In this example, the switches form the input variable because the value of output depends upon the state of these variables which shows that digital circuit can not produce same output voltage for different values of input voltage.
State the law formulated by george Simon ohm relate current to voltage and resistance?
current flow is proportional to the voltage and inversly proportional to the resistance
What component limits current in a circuit?
A resistor or an inductor. The inductor limits transient current, not steady state current.
Give the formula of state ohms law?
There is no equation for Ohm's Law. Ohm's Law simply tells us that, for ohmic or linear materials, the ratio of voltage to current is a constant.The equation you are, presumably, looking for is derived from the definition of the ohm, not from Ohm's Law, and that is resistance is voltage divided by current.
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 do parallel circuit NOT have in common with series circuit?
A parallel circuit is different in many ways from a series circuit: 1. In parallel, the voltage across all the devices connected is the same. 2. If a fault occurs in any device connected in parallel combo, then it has no effect on the operation of the other device. 3. In series circuit the current flowing through all the devices is the same while in case of the parallel one the voltage across all the devices is same.
Can you connect an AC source in series to DC source - then what happens to the current under a steady state condition?
With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.
State one example of an automatic Voltage system that is error actuated?
An AVR circuit, the voltage sensing unit measures the incoming voltage and compares it to the set point. Then an error signal is produced and sent to the amplifier,the error signal then reaches a firing circuit which consists of a thyristor with a field current which will adjust alternators output current. Dependant on the signal from the actuating unit.
What happens when you remove one bulb from a series circuit?
Answer: it will burn out **Explain:**The same current flows through each part of a series circuit. If the circuit is broken at any point there won't be any current that will flow. In this case, if one of the bulbs blew out, the other bulb would not be able to light up because the flow of electric current would have been interrupted. #Carryonlearning
What are linear and nonlinear circuits?
Linear (Straight) circuit: An electronic circuit where the info sinusoidal flood of recurrence f give a stead state yield. This circuit take after ohms law and the estimation of electronic parts doesn't change with the level of voltage of current in the circuit. Non-Linear (Non direct) circuit: The circuit in which the parameters change as for current and voltage. The parameter esteem like resistance, capacitance, inductance, waveform, recurrence and so on, is not consistent. This circuit doesn't take after ohms law and the v-i attributes are not a straight line.
Does voltage flow through a circuit or is it established across a circuit?
The 'charges' (electrons, in the case of a metal conductor) are ALREADY distributed within the conductor. They are in a state of constant, haphazard, movement at just short of the speed of light. When a potential difference is applied across the conductor, there is a tendency for these electrons to move from the negative potential towards the positive potential. This tendency is VERY slow; for example, an individual electron is unlikely to pass through the filament of a flashlight during the lifetime of its battery!

Why are domestic electric lamp circuits are connected in parallel?
If connected in series, the same current passes thru all the appliances. So, always all of them are in the same state ie all of them are running or all of them are idle. Also, if any one appliance malfunctions, it prevents current frm flowing to the other appliances and thus they also dont work. So, home appliances are always connected in parallel.Source(s):
Can a constant dc current can induce a steady state voltage in a transformer?
No, the current has to change for a voltage to be induced in the transformer.
What happens if you use a fuse that's overrated for voltage but has the correct current rating?
Using a fuse correctly rated for current but "overrated" for voltage does not present a problem. Current ratings are critical safety issues, and fuses should be replaced with those of the same current rating. But using a fuse with an identical current rating but a higher voltage rating is not a problem. The reason for that lies in what the voltage rating of a fuse is. Fuses are given a voltage rating to state a maximum voltage in a circuit that they are designed to protect. And the voltage rating has nothing to do with the "normal" operation of the fuse. The fuse carries current when it operates normally, but when something happens and excessive current flows, the fusible link heats up and opens. This is where the voltage rating comes into play. It is possible that a fuse can arc through when it fails. It is the voltage rating that stands in the way of this. As long as the voltage rating of a circuit is not beyond the voltage rating of the fuse, that fuse will fail safely when it fails. It is acceptable to use a fuse of an equal current rating but a higher voltage rating when replacing a fuse that has failed.
