Exempel på hur man kan använda OHMS i en mening

• For a quantitative assessment, quality HF receivers are calibrated so that S9 on the S-meter corresponds to a signal of 50 μV at the antenna standard terminal impedance 50 ohms.
• Complex impedance is a quantity measured in ohms which represents resistance as positive real numbers in the usual manner, and also represents reactance as positive and negative imaginary values.
• It is lowest for feedpoints located at a point of maximum current (an antinode), and highest for feedpoints located at a point of minimum current, a node, such as at the end of the element (theoretically, in an infinitesimally thin antenna element, radiation resistance is infinite at a node, but the finite thickness of actual antenna elements gives it a high but finite value, on the order of thousands of ohms).
• Typical nominal impedances for speakers include 4, 6, 8 and 16Ω (ohms), with 4Ω being most common in in-car loudspeakers, and 8Ω being most common elsewhere.
• where resistance in ohms and capacitance in farads yields the time constant in seconds or the cutoff frequency in Hz.
• Transmitters feed power into a resistive load, very often 50 ohms, for which the transmitter is optimally designed for power output, efficiency, and low distortion.
• The internationally standardized symbol for a resistor is therefore now simplified to an oblong, sometimes with the value in ohms written inside, instead of the zig-zag symbol.
• Conversion of per-unit quantities to volts, ohms, or amperes requires a knowledge of the base that the per-unit quantities were referenced to.
• Conversely, a headphone output generally has a source impedance of only a few ohms (to provide a bridging connection with 32 ohm headphones) and will easily drive a line input.
• The primary constants are the electrical properties of the cable per unit length and are: capacitance C (in farads per meter), inductance L (in henries per meter), series resistance R (in ohms per meter), and shunt conductance G (in siemens per meter).
• This is a level of 50 microvolts at the receiver's antenna input assuming the input impedance of the receiver is 50 ohms.
• The amount of attenuation can be calculated for any given frequency; the result is called the capacitive reactance, which is an effective resistance measured in ohms:.
• The OTA has a gain measured in units of transconductance (siemens) whereas the Norton amplifier has a gain measured in units of transimpedance (ohms).
• 636 has a rheostat (formed by 16 cast iron resistors connected in series, for a total resistance of 29 ohms) that needs to be gradually, but as soon as possible, excluded on start-ups, which regulates the current to the six 32R-200 DC traction motors, two per bogie.
• There are some commercial bridges reaching accuracies of better than 2% for resistance ranges from 1 microohm to 25 ohms.
• In an era when the NAD's rated power output of 20 watts per channel continuous into 8 ohms was considered anaemic, the manufacturer claimed it could deliver much stronger power output into lower impedances under dynamic conditions (music or peak power output).
• A typical phasor has separate controls to adjust the phase of the current going to each tower, adjustable power divider controls, and a common point impedance matching network to adjust the system input impedance to 50 ohms with no reactance without disturbing the phase or amplitude of the tower currents.
