Examples

  • A good EEG signal should have less than 50 kilo-Ohms of impedance.

  • In applying Ohm's law to an alternating current circuit, impedance must be substituted for resistance.

  • Find the reactance of a choke coil having a resistance of 10 ohms, when its impedance is 50 ohms.

  • In all such cases the impedance which the circuit offers is made up of two things—resistance and inductance.

  • The battery supply to the operator's transmitter is through an impedance coil 9.

  • These conditions are satisfied by using in the impedance coil many turns of large wire and an ample iron core.
