What are the roles of capacitors in electric or electronic circuits ? Our website is made possible by displaying online advertisements to our visitors. what happens to the impedance when the frequency increases?

Thanks for correction. Ohm’s Law.

Step by Step Procedure with Solved Example, Electrical Wire & Cable Size Calculator (Copper & Aluminum), Resistance, Conductance, Impedance and Admittance Formulas. Now we increased the frequency form 50Hz to 60Hz. [closed] Ask Question Asked 7 months ago. When resistance increases, the circuit current decreases and vice versa.

We can get this from Transformer universal emf equation. In an RC series circuit ( see Fig. Up tp 93% Off - Launching Official Electrical Technology Store - Shop Now! The important parameters for a electrical transformer are voltage, current & its frequency and losses associated. How to Calculate the Battery Charging Time & Battery Charging Current – Example. Limited Edition... Book Now Here. Why Power Factor Decreases When Capacitive Reactance Increases or Capacitance Decreases? Inductive reactance is a kind of resistance. Why Current Decreases When Inductance or Inductive Reactance Increases? How To Calculate Your Electricity Bill. Why the reactance of a system under fault condition is low and faults currents may raise to the dangerously high value? I ∝ 1 / L     and     I ∝ 1 / XL    and I ∝ 1 / Z, In inductive ckt I=v/z I= 3000/33.63 =89.26 A not 82.20. But when circuit frequency increased from 50Hz to 60Hz, then the current decreased from 89.20 A to 75.83 A. Why Current Increases When Capacitance Increases or Capacitive Reactance Decreases? To better picture what happens in the above two scenarios, hold voltage and current constant in turn and then use Ohm’s law to see what happens each time. Active 7 months ago.

How do you Explain? Transformer universal emf equation. The term "impedance" is a general term for any combination of resistance, capacitive reactance and inductive reactance. What happens to the voltage across an inductor as the frequency increases? We depends on ad revenue to keep creating quality content for you to learn and enjoy for free. In an inductive circuit, when frequency increases, the circuit current decreases and vice versa. In a capacitive circuit, when frequency increases, the circuit current also increases and vice versa.

Why Power in Pure Inductive and Pure Capacitive Circuit is Zero? Easy & Simple Explanation.

25% Off on Electrical Engineering Shirts. Voltage of a transformer at a given flux density increases with frequency and also decreases with it. According to Ohm’s Law, I ∝ V, But I ∝ 1/V in Power Equation. What is the disadvantage of low power factor? Answer Save. Now Say a transformer is designed for 50 Hz frequency but if the frequency becomes high or low what would happen. In an inductive circuit, when frequency increases, the circuit current decreases and vice versa. if frequency of a transformer is increased, what happens to output voltage? Why Current Decreases When Inductance or Inductive Reactance Increases? How to Calculate/Find the Rating of Transformer in kVA (Single Phase and Three Phase)? We can see that, When frequency was 50Hz, then the circuit current were 89.20 A. Your email address will not be published. Lv 5. Required fields are marked *, All about Electrical & Electronics Engineering & Technology.

But with high frequency there is increase in transformer losses like core loss and conductor skin effect. Why Power Factor Decreases When Inductance or Inductive Reactance Increases? Get Free Android App | Download Electrical Technology App Now!

Why the reactance of a system under fault condition is low and faults currents may raise to the dangerously high value? – Examples in British and SI System, Thevenin’s Theorem. Limited Edition... Book Now Here.

XC = 1 / 2πfC = 1 / (2 x 3.1415 x 60 x 5×10-6) = 530.63Ω.
