ohms per volt造句
例句与造句
- The sensitivity of an analog multimeter is given in units of ohms per volt.
- The meter movement itself is 20, 000 ohms per volt and 50 microamperes full scale.
- An improved version of 1927 increased this to 13-ranges and 166.6 ohms per volt ( 6 mA ) movement.
- After 1945 / 6, 20, 000 ohms per volt became the expected standard for electronics but some maker offered even more sensitive instruments.
- For example, a very low cost multimeter with a sensitivity of 1000 ohms per volt would draw 1 milliampere from a circuit at full scale deflection.
- It's difficult to find ohms per volt in a sentence. 用ohms per volt造句挺难的
- Between the mid 1930s until the 1950s, 1000 ohms per volt became a de facto standard of sensitivity for radio work and this figure was often quoted on service sheets.
- The sensitivity of such a meter can be expressed as " ohms per volt ", the number of ohms resistance in the meter circuit divided by the full scale measured value.
- A " Universal " version having additional alternating current and alternating voltage ranges was offered from 1933 and in 1936 the dual sensitivity Avometer Model 7 offered 500 / 100 ohms per volt.
- The technical specifications of these devices were often crude, for example the one illustrated has a resistance of just 33 ohms per volt, a non-linear scale and no zero adjustment.
- A power factor and wattage unit was also available ) . 500 ohms / volt with divide by two button in normal position, 1000 ohms per volt with divide by two button pressed.
- However, some manufacturers such as Simpson, Triplett and Weston, all in the USA, produced 20, 000 ohm per volt VOMs before the Second World War and some of these were exported.
- The movement drew 12mA for full-scale deflection and used a " universal shunt " permanently in parallel with the movement which increased the input terminal full-scale current to 16.6mA, corresponding to 60 ohms per volt.
- Its maximum current draw of 50 ?A at full-scale deflection ( corresponding to 20, 000 ohms per volt ) is sufficient in most cases to reduce voltage measurement error due to circuit loading by the meter to an acceptable level.
- For example, a meter with a sensitivity of 1000 ohms per volt would draw 1 milliampere at full scale voltage; if the full scale was 200 volts, the resistance at the instrument's terminals would be ohms and at full scale the meter would draw 1 milliampere from the circuit under test.
- The first Avometer had a sensitivity of 60 ohms per volt, three direct current ranges ( 12 mA, 1.2 A, and 12 A ), three direct voltage ranges ( 12, 120, and 600 V or optionally 1200 V ), and a 10, 000 ohm resistance range.
