Why is voltage a minimum at resonance?

The variation of impedance and current with frequency of Voltage and Current in Series Resonant Circuit is shown in Fig. 8.7. At resonant frequency, the capacitive reactance is equal to inductive reactance, and hence the impedance is minimum.

What is the condition for resonance?

The conditions to produce resonance in an object are: The object must have a minimum of one natural frequency of vibration. The object must be driven by an external force of vibration. The frequency of the external vibrating force must be similar to the object’s natural frequency of vibration.

What is resonance effect give necessary condition for resonance?

The concept of resonance effect tells about the polarity induced in a molecule by the reaction between a lone pair of electron and a pi bond. It also occurs by the interaction of 2 pi bonds in the adjacent atoms. Resonance in simple is the molecules with multiple Lewis structures.

What do you understand by the term resonance give two conditions for producing resonance?

Resonance : “is a special case of forced vibrations. This phenomenon is called resonance.” Two conditions of resonance : 1. The natural frequency of the given body non-vibrating body must be equal to or its integral multiple the frequency of the vibrating body. 2. The vibrating body must have sufficient force so as to.

How does the voltage through each resistor relate to the total voltage through the power supply in a parallel circuit?

The voltage across each resistor within a parallel combination is exactly the same but the currents flowing through them are not the same as this is determined by their resistance value and Ohms Law. Then parallel circuits are current dividers.

Is voltage across series resistors the same?

When resistors are connected in series, the current through each resistor is the same. When resistors are connected in series, the total voltage (or potential difference) across all the resistors is equal to the sum of the voltages across each resistor. …
