rude man said:4.7K ohms.
chan1 said:what about when frequency is 100hz, 1khz 10khz? what's th impedance
thanks
Impedance is a measure of the opposition to the flow of an electric current. It is important in science because it helps us understand how electricity behaves in different circuits and systems.
Impedance is calculated using the formula Z = R + jX, where Z is impedance, R is resistance, and X is reactance. Reactance takes into account the capacitance and inductance in a circuit.
Resistance is a measure of how much a material or component resists the flow of current, while impedance takes into account both resistance and reactance.
Yes, impedance can be negative in certain circuits. This indicates that the current and voltage are out of phase with each other.
Impedance is used in many practical applications, such as designing audio systems, calculating power in electrical systems, and analyzing the performance of electronic components.
