The ohmmeter differs from other types of meters in that it has its own?
Electric supply, usually a battery.

You first patent it, but check out how that works in your country because it differs.
What is reactance modulator?
= A Reactance Modulator =A reactance modulator changes the frequency of the tank circuit of the oscillator by changing its reactance. This is accomplished by a combination of a resistor, a condenser, and a vacuum tube (the modulator) connected across the tank circuit of the oscillator as in Fig. 33 A, and so adjusted as to act as a variable inductance or capacitance. Fig. 33 A. Principle of a reactance modulator The net result is to change the resonant frequency of the LC circuit by amounts proportional to the instantaneous a.f. voltages applied to the grid of the modulator tube, without changing the resistance of the LC circuit or the amplitude of the oscillations. A modulator circuit is shown in Fig. 33 B. Fig 33 B. A reactance modulator The voltages supplied to both the modulator and oscillator must be carefully stabilized to prevent undesired frequency changes. The speech amplifier (Fig. 33 A) does not have to deliver any power and need supply only a small output voltage, say 10 or 15 volts. A pentode and triode, R-C coupled, will be sufficient even with a sensitive microphone and a high-powered oscillator. The frequency change of LC per volt change on the a.f. grid of the modulator tube will be greater when C1,Fig. 33 B, is made smaller. The blocking condenser C2 has a comparatively high value, and hence offers but small reactance to r.f. currents. Fig. 19 H. An RC phase shifter In Fig. 33 B, the radio-frequency voltages which are developed across the tank in the oscillator circuit also appear across the RC1 circuit and across the parallel 6L7 modulator tube. Now look up the phase-shifting circuit of Fig. 19 H. The resistance r has been replaced by the internal resistance of the modulator tube of Fig. 33 B. The voltage drop across C1 is 90° out of phase with the tank voltage. It is applied to the control grid of the 6L7 whose r.f. plate current responds in the same phase. Thus this current is made to lag 90° behind the tank voltage. The r.f. plate current flows through the tank circuit and, combined with the current therein, is equivalent to a new current whose phase differs from the normal value just as though an additional reactance (not resistance) had been connected in with L and C. This, of course, changes the frequency of the LC circuit and hence of the transmitter. When a.f. is fed into the modulator tube, it causes proportionate changes in the r.f. plate current and hence in the equivalent reactance of the LC circuit.
Why is the frequency of operation in Nigeria 50Hz but it differs elsewhere?
The frequency of operation was decided by the government before they started building their power plants.
What is the salary of the governor?
The salary of state governors differs from state to state. The governor of California receives $250,000. The governor of New Hampshire receives $40,000.

How the direction of electric current differs from the direction of electrons in a circuit?
Circular,,,from the word circuit.
How an op amp differs from a basic amp?
A basic, single transistor amplifier differs from an op amp: 1. The op amp has more gain 2. The op amp may have higher input resistance (so it loads the circuit less) 3. The op amp may have a lower output resistance (so it can drive larger currents) 4. The op amp likely has a lower frequency response (due to the high gain, unless you provide some sort of feedback loop) 5. The op amp is ridiculously complex compared to a simple amplifier 6. The op amp will require a positive and negative voltage (may be unnecessary with a single transistor amplifier)
Why main circuit boards always switch on at upwards in electric meters?
Not necessarily so- this differs in different countries.
What can one expect to pay for a Pioneer Amplifier?
One can expect to pay above 100 USD for a decent one, with an acceptable amplifying rate. The price differs depending on the quality of the sound and the better quality often costs a small sum extra.
Definition for time current curve?
It is the relationship between current and time on a circuit breakers opening. When the circuit breaker needs to open in given "windows" of amps and time. They should intersect on the curve to indicate proper circuit breaker functioning. The timing and current value should coincide with each other, per manufacturers specifications. Each breaker differs.
How transformational leadership differs from previous leadership concepts?
Transformational Leadership differs from previous leadership concepts in that it focusses on the relationship between the leader and follower. There is an increased level of moral and ethical focus, and the leader is interested in the well being of the person being lead, not just getting the job done. Previous leadership concepts focus on the leader themselves, and what traits and behaviours the leader has. Typically they are focussed on a transactional interaction between leader and follower: ie: You do this job, and get this reward, or punishment, accordingly. Transformational leadership is focussed more on the quality of interation between people. It has an inspiring, uplifting, stimulting and individualised focus. The results are still important, but it is about long term relationship building.
How are osmosis differs from diffusion?
it differs with low consentration and high concentraction
What is the difference between district courts circuit court?
It really depends what kind of courts you are talking about and where the courts are. If the courts are federal, then a district court is a trial court and a circuit court is an appeals court, which may review a trial decision from a district court. For state courts, the difference between a district court and a circuit court will depend on what state the courts are in. Many states have courts called "district court" and "circuit court," but what kinds of cases these courts handle differs state to state.
