How does the number of cells affect the current in a circuit?
More cells = more available power. Power = voltage * current. The orientation of the cells determines whether this power is delivered as more voltage, or more current. If the cells are in series, the voltage will increase proportionately and the available current will remain unchanged; if the cells are in parallel, the current will increase proportionately and the voltage will remain unchanged.
In a purely resistive ac circuit the current and voltage?
Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.
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 are the advantages and disadvantages of such high voltage?
voltage is termed as electrical pressure. when high voltage is applied more is the movement of electrons. hence losses will be less. this is one of the major reason for which high voltage transmission is chosen.secondly due to high voltage the current will be less so as the conductor size
How does the voltage applied to a circuit affect the current flowing through the wire?
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
Is 0.01 Milli ampere is dangerous?
How high is the voltage that is being used? With high enough voltage any current is dangerous.
Which is the dangerous current?
You can't really separate them. It's the current flowing through your body that does the damage, but the value of the current depends on the voltage across your body -the higher the voltage, the higher the resulting current.
What is the lowest value of current that may cause death?
It is difficult to define the value which may cause death. I think it the voltage which is dangerous. Approximately a voltage of 50V is dangerous for heart.
Which is more dangerous high-current or high-voltage?
current is the killer not volts, you can have thousands of volts but with out flow (current) the danger is minimal, but if you have voltage its very easy to induce current so be careful and let a professional take care of it if you do not know what you are doing.
What is current gain and voltage gain?
Current gain is the ratio of output current divided by input current. Voltage gain is the ratio of output voltage divided by input voltage. Nothing more complicated than that.
How does the number of cells affect the current in a circuit?
More cells = more available power. Power = voltage * current. The orientation of the cells determines whether this power is delivered as more voltage, or more current. If the cells are in series, the voltage will increase proportionately and the available current will remain unchanged; if the cells are in parallel, the current will increase proportionately and the voltage will remain unchanged.
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
Who is dangerous ac or DC supply?
ac because thats the accelerated current. and it has way higher voltage. dc direct current hs low voltage and wont hurt as bad
How can electric current be changed in Omh's Law?
Ohm's Law: V = IR Solving for current: I = V/R To affect the current, you can either change the voltage (more voltage --> more current), or the resistance (more resistance --> less current).
Simple example for difference between current and voltage?
Voltage is the number of electrons relative to another location; current is how many of those electrons are moving from one location to another. A simple example is a stream. Think of voltage as the width and depth of the stream, and current as how fast the stream is moving. If it is very big, but not moving, it is not very dangerous. Alternatively, if it is very small and moving quickly it is not really dangerous. But if it is big and moving quickly, it becomes dangerous.
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
Why alternating current is more dangerous than the direct current?
Edison, the inventor of DC, tried his hardest to convince the public that Tesla's AC that was more dangerous, but DC is far more dangerous. If you are shocked wit high-current DC, you do not have a "kickback" type reaction where you will jump away from the wire. Instead, the constant signal of DC causes you to hold on to the wire against your will, worsening the shock.
