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.

State two rules for the voltage and current in a series circuit?
Kirchoff's voltage law and Kirchoff's current law
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.
What are the characteristics of a simple circuit?
A simple circuit consists of a source of electro motive force ( EMF or voltage V ) This could be a battery,dynamo or solar cell. The circuit should do something, like light a lamp. For the lamp to glow there must be a flow of electrons called an electric current measure in Amperes (I). For the current to flow the circuit must form a closed loop, like a daisy chain. A switch is a device that breaks this loop and controls the state of the circuit. Closed circuit, switch closed, = lamp on Open circuit, switch not closed = lamp off
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.
AC operation of magnetic circuit?
DC sources are not used for excitation of magnetic circuit of transformers and other AC machines. AC sources are used. The steady-state current is calculated by the applied voltage and resistance of the circuit when DC excitation is applied. The inductance in this case plays the role only for the transient part. The adjustment of the magnetic flux takes place as per the value of current to satisfy the relationship of B-H curve or magnetization curve. For the case of AC excitation, inductance comes into picture for steady-state performance. The flux is determined by the impressed voltage and frequency. The adjustment of magnetization current takes place as per the value of this flux to maintain the relationship imposed by the magnetization ....

What is indicated by reading of battery voltage on the ground side of component?
That a short to ground exists in 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 the voltage drop through resistor 1?
There is insufficient information in the question to properly answer it. You don't state the value of resistor 1, nor do you state how it is connected in the circuit, nor do you state the value of the other components in the circuit. Please restate the question, giving more details.
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!
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.
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.
Positive logic in a logic circuit is one in which?
In Positive logic, we all assume that the more positive (binary) voltage state is One, the less positive voltage state is Zero.Both voltage states could be positive, both could be negative, or they could be opposite polarities.
What is voltage level of RS-232?
RS-232 is ±3 to ±15, with a maximum short circuit survivability rating of ±25. Typical implementations see ±12. The negative voltage is the marking state, or the one state at the USART level. The positive voltage is the spacing state, or the zero state at the USART level. In terms of control signals, such at DTR or CTS, MARK (negative) is false, and SPACE (positive) is true. Zero volts is invalid, representing a break state.

State four types of LC oscillators?
Four types of LC oscillators include voltage controlled oscillators, drift control oscillators, crystal oscillators, and tuned circuit oscillators. A tuned circuit oscillator is the most common type of oscillator.
What is the function of a logic probe?
To tell you the state of a logic signal, when the state changes are infrequent and the cost of an oscilloscope or logic analyzer would be inappropriate/excessive.
