Current and voltage readings taken on the far right of a meter's scale provide greater inaccuracy that readings taken from mid scale on the meter.

The greater the what the less current there is for a given voltage?

Resistance is probably the missing word. I = e/R. If R is greater, I is less.


Why common emitter configuration is preferred?

Reason: The common Emitter mode has voltage and current gain better than the other two configurations(CB and CC). i.e it has a current gain greater than that of CC mode and greater voltage gain than that of CB mode.


What happen if you interchange the current and voltage probes of four probe?

If you interchange the current and voltage probes in a four-probe measurement setup, you will likely obtain incorrect readings. The current probe is designed to measure the current flowing through the sample, while the voltage probes measure the voltage drop across the sample. Reversing them can lead to inaccurate voltage measurements and potentially damage the equipment or the sample due to improper current flow. This error can also affect the calculated electrical properties, such as resistivity.


What are the reasons that low frequency parameters cannot be Measured in microwaves?

(a) voltage and current readings vary with position along the transmission line, (b) voltage and current are difficult to define in non-TEM transmission lines.


What happen when voltage decreases and current increases?

Yes. As long as the load stays the same. Voltage equals the resistance of the load times the current or amperage. Or , in this case, as an example, if the load is the same, the voltage is 240 and current is 10 amps. At 120 volts, the current is 20 amps. Current x resistance(or the load)=voltage. With simple math, the equation can be moved around.

What is the Primary function of a voltage follower circuit?

Its purpose is to provide approximately the same voltage to a load as what is input to the amplifier, but at a much greater current. In other words, it has no voltage gain, but it does have current gain.


Why are the readings on a ammeter always different?

The readings on an ammeter indicate the current being drawn by a load in a circuit. This load is basically a resistance to current flow. The higher the resistance, the lower the current. The supply voltage has a direct effect on current flow. The higher the voltage applied, the higher the current will be. So the readings will vary on the ammeter according to fluctuations in load and or resistance of the circuit and the applied voltage.

How can you mesure AC?

AC (alternating current) can be measured using an AC voltmeter or an oscilloscope, which can display the voltage waveform and frequency. A clamp meter can also be used to measure the current without breaking the circuit. Additionally, a multimeter set to the AC measurement mode can provide readings of voltage and current in AC circuits. It's important to ensure that the measuring device is rated for the specific voltage and current levels in your application.


What is the relationship between voltage potential and electrical current flow in a circuit?

Voltage potential is the force that pushes electrical current through a circuit. The higher the voltage, the greater the potential for current flow. In other words, voltage drives the flow of current in a circuit.


Why do two ideal voltage source of unequal voltage cannot be connected in parallel?

If two ideal sources of unequal voltage are connected in parallel the higher voltage will provide a majority of the current (a two percent difference in voltage would provide an additional 5% of the current) and (in the case of batteries) the larger would provide charging current, quickly draining it.


Is emf current greater than current?

EMF is electromotive force. It is another name for voltage. Voltage is electric potential in joules per coulomb. Current is electric flow, in amperes. Amperes are coulombs per second. Voltage and current are not the same thing, and "emf current", or "voltage current" does not make sense.


What happen to the current when the voltage is greater than or equal to 6 volts?

The current is greater than or equal to (6) divided by (the effective resistance of the circuit).


An increase in voltage causes a greater?

An increase in voltage causes a greater electric current to flow in a circuit, assuming the resistance remains constant, based on Ohm's Law. This relationship is described by Ohm's Law as V=IR, where V is voltage, I is current, and R is resistance.


What is Difference Between Current Source and Voltage Source?

A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).


What would induce a greater electric current in a wire?

A greater electric current in a wire can be induced by increasing the voltage applied across the wire or decreasing the resistance of the wire. Both factors contribute to Ohm's Law (V=IR), where V is voltage, I is current, and R is resistance. Increasing the voltage or decreasing the resistance will lead to a higher current flowing through the wire.
