An ideal voltage source charges capacitor in?

A: A voltage source Will charge a capacitor to 63% of its input value, The value to get there is stated a Resistance time capacitor as time. Mathematically it will never get there but engineering consider 5 times RC time constant as close enough,


What causes the ripple voltage on the output of a capacitor-input filter?

Ripple voltage in a capacitor-input filter primarily arises from the charging and discharging cycles of the capacitor. When the rectifier conducts, the capacitor charges to the peak voltage of the input signal. As the load draws current, the capacitor discharges, causing the voltage to drop until the rectifier conducts again, resulting in a voltage ripple. The magnitude of this ripple depends on factors such as the load current, capacitance value, and input frequency.


Explain the Potential across the resistor during the charging and discharging process of the capacitor?

The voltage across a capacitors given as a time constant t= 63% the resistor value multiply buy capacitor value. it doesn't matter if it goes more or less negative it will follow this function


Is solar panel a constant current source?

No. A battery is a constant voltage source. Batteries are sold as having a specific voltage (1.2 volts, or 1.5 volts per cell), not a specific current.


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.

An ideal voltage source will charge an ideal capacitor?

An ideal capacitor is characterized by a single constant value for its capacitance.


WHAT WOULD happen if you keep charging time shorter than time constant?

If you keep the charging time shorter than the time constant, the capacitor will not fully charge to its maximum voltage. The voltage across the capacitor will reach approximately 63% of the final value after one time constant. Therefore, if you stop charging before the capacitor fully charges, the voltage across the capacitor will be lower than expected.

Why is capacitace inversely proportional to voltage?

Capacitance is not inversely proportional to voltage, rather capacitance is a measure of how much charge a capacitor can hold for a given voltage. The capacitance value remains constant regardless of the voltage applied across the capacitor. The relationship between capacitance, voltage, and charge is governed by the formula Q = CV, where Q is charge, C is capacitance, and V is voltage.


What does the volt on a capacitor mean?

the voltage number on the capacitor indicates that the capacitor can with stand to that particular voltage across it.generally during design, the value of capacitor will be selected in such a way that this voltage rating should be double than what really we get in the circuit


Why is the charging time of a capacitor lower than the discharging time?

The charging time of a capacitor is usually lower than the discharging time because during charging, the voltage across the capacitor is increasing from zero to its maximum value, which initially allows a higher current to flow. During discharging, the voltage across the capacitor is decreasing from its maximum value to zero, resulting in a lower current flow. This difference in current flow affects the time it takes for the capacitor to charge and discharge.


Why does a dual voltage motor draw more current when connected to low voltage than it does when connected to high voltage?

As we know that P=VI, and P is a constant value for any particular motor, so if the voltages will drop current will increase so that the product of V and I be the that particular constant value for any particular motor

How do you increase the value of a capacitor?

A: Any additional capacitor added in parallel will effectively increase to total capacitance by that value. Note that additional capacitor added must have the same voltage rating as the other
