In general form,即是Ry=R′R′′∑RΔRy=R′R″∑RΔ(R,R′′R,R″是yy邻接的电阻) Potential Divider Circuit 串联分压 对于串联的两电阻R1,R2R1,R2,流过他们的电流I1=I2I1=I2 因此有V1/V2=I1R1/I2R2=R1/R2V1/V2=I1R1/I2R2=R1/R2 若总电动势为VSVS,则V1=VSR1R1+R2V1=VSR1R1+R2...
How does an inductor behave in a circuit? If you have a constant current, then there is no change (DC current) and thus no potential difference across the inductor---it acts like it's not even there. If there is a high frequency current (AC circuit) then there will be a large poten...
Reactance is the opposition to the changing current that the capacitance and the inductor in the circuit offer. The inductive reactance varies directly with the frequency, and the capacitive reactance varies inversely with the frequency.Answer and Explanation: Given data The capacitan...
Between 10 kHz and 1 MHz (the range of switching frequencies for most IC switching regulators!) the impedance is limited by the ESR to 0.2 Ω. Above about 1 MHz the capacitor behaves like an inductor due to the ESL of 20 nH. These values, although they may vary somewhat depending on ...
In a pure capacitive circuit, the instantaneous power may be positive or negative. As with the simple inductor circuit, the 90-degree phase shift between voltage and current results in a power wave that alternates equally between positive and negative. This means that a capacitor does not dissipa...
Current in LC circuit becomes maximum when resonance occurs. So, omega=1/(sqrt(LC))=1/(sqrt(1xx25xx10^(-6)))=1000/5=200rad//sec An alternating e.m.f of frequency is v(=1/(2pisqrt(LC)))
