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.
Resistance is probably the missing word. I = e/R. If R is greater, I is less.
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.
(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.
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.
A: That will happen anytime the voltage source is not able to provide the power needed for the load. If the load exceed the power available from the source the voltage will be reduced as IR drop from the source
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.
The readings on an ammeter are different because they measure the current flowing through a circuit at that specific point in time. Current can vary due to changes in the circuit components, resistance, and voltage. These variations result in different readings at different moments.
...what readings? current? voltage? power? lux?
true
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.
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.
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.
The current is greater than or equal to (6) divided by (the effective resistance of the circuit).
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.
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).
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.
You can measure electrical units such as voltage, current, and resistance using specific electrical measuring instruments like multimeters. Voltage is measured in volts (V), current in amperes (A), and resistance in ohms (Ω). These instruments provide accurate readings to help troubleshoot electrical systems and devices.
