What is the v-i characteristics of solar cell?
The V-I (voltage-current) characteristics of a solar cell show the relationship between the voltage applied across the cell and the current generated by the cell. At zero voltage, a solar cell generates its maximum current (short-circuit current), while at zero current, the cell generates its maximum voltage (open-circuit voltage). The V-I curve gives an insight into the performance and behavior of the solar cell under different operating conditions.
Vi characteristics 0f a solar cell?
the VI characteristics graph for a solar cell lies in the third quartering of the graph as both I and V come out to be -ve for the mode of operation ie active region. there are even some value at the dark that is called dark current, better explanation is given in the book by A P Malvino, electronic principles.
What happened to the reading of ammeter and voltmeter if the number of dry cells are added in the circuit?
Well, isn't that just a happy little question! When you add more dry cells to a circuit, the ammeter will show a higher reading because there is more current flowing through the circuit. The voltmeter reading will also increase because the total voltage of the circuit will be higher with the addition of more dry cells. Just remember to always paint with light and electricity in your circuits, my friend!
What will an ammeter show if the circuit is broken?
Zero. No current is flowing in an open circuit. The ammeter will display an amount of 0 amps because there is no longer any current once the circuit has been broken. An ammeter measures current.
What is needed to demonstrate transformation of energy with a circuit board?
To demonstrate transformation of energy with a circuit board, you would need a power source (such as a battery), components like resistors, capacitors, and LEDs to manipulate the energy, and a multimeter to measure voltage and current. By connecting these components in a circuit, you can show how electrical energy can be transformed into different forms such as light, heat, or sound.
Why the voltage drop across inductance and voltage drop across capacitance is greater than source voltage in series resonance circuit?
The reason for the total voltage drops across the capacitance and inductance IN AN AC CIRCUIT has to do with the different phase angles of the voltages.First, current is the same value and same phase angle everywhere in a series circuit. But, voltage across a capacitor lags current by 90 degrees (capacitor current leads voltage). Next, voltage across a pure inductance leads current by 90 degrees (inductor current lags voltage).The rule that all voltages in a series circuit have to add to the supply voltage still applies, but in this case, the voltage drops are added VECTORALLY, not arithmetically. If you were to graph this addition, you would show any resistance voltage in phase with the current, the capacitor voltage at -90 degrees to the current and the inductor voltage at +90 degrees to the current, for a phase difference between them of 180 degrees, cancelling each other out.In a series resonant circuit, the impedances of the capacitor and inductor cancel each other. The only impedance to the flow of current is any resistance in the circuit. Since real-life inductors always have some resistance, at least there is always some resistance in a series resonant circuit.

Can you show me how to solve for conductance in a dc circuit please show example?
The conductance between any two points in any DC circuit is(current between the two points)/(voltage between the two points) .

Can kirchoff's voltage law be used to determine voltage drop?
Yes. Kirchoff's Voltage Law states that the signed sum of the voltage drops going around a series circuit is zero. Thus, if you know all but one, you can figure it out. You simply add what you know up, and what is left is the last drop. Don't forget to be consistent in your use of signs. If, for instance, you show a voltage or current source as a voltage rise, then it must be considered to be a negative voltage drop. Or vice versa, as the case may be.
What is the significance of negative values of voltage and current?
What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
What effect does a diode have on a series circuit in which the voltage source changes polarity periodically that is and alternating current circuit?
In a series circuit with an alternating current (AC) voltage source, a diode allows current to flow in only one direction, effectively converting the AC into direct current (DC). This means that during one half of the AC cycle, the diode conducts and allows current to pass, while during the other half, when the polarity reverses, the diode blocks the current. As a result, the output voltage across the diode will typically show a pulsating DC waveform, characterized by peaks corresponding to the positive half-cycles of the AC input. This rectification process is fundamental in power supply applications where DC is required.
What is the voltage if the current is 0.4 and the resistance is 3?
If the current is 0.4 and the resistance is 3 the voltage is 1.2 V

How can I use a multimeter to check for power in a circuit?
To check for power in a circuit using a multimeter, set the multimeter to the voltage setting, connect the black probe to the ground and the red probe to the positive terminal of the circuit, and read the voltage displayed on the multimeter. This will show if there is power flowing through the circuit.
What will an ammeter show if the circuit is broken?
Zero. No current is flowing in an open circuit. The ammeter will display an amount of 0 amps because there is no longer any current once the circuit has been broken. An ammeter measures current.
What is a circuit diagram of a voltage stabilizer?
It's a diagram showing the components and connections needed to build a voltage stabilizer. The diagram will show a power transistor and a voltage reference, such as a zener diode.
