What happens in a circuit at resonant frequency?
what is resonant frequency
What is the condition of maximium power transfer of circuit?
Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
What happens when you stick a core into a coil inductor in an undriven circuit?
If the circuit is undriven, there is no power, so inserting a core does nothing. In general, however, inserting a core into an inductor increases its inductance. Depending on the circuit, that lowers the resonant frequency.
What happens when lagging Power Factor changes to leading PF?
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
What happens to the speed of an induction motor if the supply frequency is increased?
The supply frequency determines the synchronous speed of the machine -i.e. the speed of the naturally-rotating field within the airgap. As motors typically run around 5% below this speed, the rotor's speed would increase.
What happens to the current in a circuit when the resistance is increased?
The flow of electrons meets an increased impedance to it's flow.
When the resistance in a circuit is increased what happens to the current?
The flow of electrons meets an increased impedance to it's flow.
What happens to the resistance when the frequency is doubled?
When the frequency is doubled, the resistance of a circuit remains unchanged. Resistance in a circuit is independent of frequency and is determined by the material and physical dimensions of the resistor.
What happens when frequency is increased of transformer?
When the frequency of a transformer is increased, the core losses of the transformer increase due to increased eddy current losses and hysteresis losses. This results in a rise in temperature of the transformer. Additionally, higher frequency can affect the impedance of the transformer and alter the voltage regulation and efficiency.
What happens if capacitance is increased in parallel RC ciRCuit and series RC ciRCuit?
In both cases, the time constant of the RC circuit is increased. If the application is a high- or low-pass circuit, then the filter cutoff frequency is decreased in both cases. If the application is a phase-shift network, then the frequency for a given phase- shift is reduced.

What happens to the pitch of a note when the frequency is increased?
If the frequency of a sound is increased, the pitch goes higher.
What is the condition of maximium power transfer of circuit?
Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
What happens to the frequency of a wave when the energy is increased?
When the energy of a wave is increased, the frequency remains the same. Frequency is determined by the source of the wave and does not change with energy.
What happens to frequency if time period is increased?
If the time period is increased, the frequency decreases inversely proportionally. This is because frequency is the reciprocal of the time period. So, as the time period increases, the frequency decreases.
What happens to current in a simple circuit as potential difference is increased?
depends on the simple circuit. please describe it.
What happens to the frequency of the wave as the tension on the wire is increased?
