Why electric current across a wire drops?
Electric current does not drop. Electric voltage, however, drops across a wire because the wire has non-zero resistance. (Do not confuse electric current with electric voltage - they are not the same.)The reason current does not drop is that, in a series circuit, according to Kirchoff's current law, the current at every point in a series circuit is the same.
When you double the voltage in a simple electric circuityou double?
In that case, the current will also be doubled. This follows from Ohm's Law (current = voltage / resitance)
What type of device is used to increase or decrease the voltage of an electric current-?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
Does the amount of electric current flowing in a conductor depend in part on the pressure under which it flows?
Yes. Pressure being voltage. Voltage divided by resistance equals current.
What causes the axle to spin in an electric motor?
Switching the field voltage to the coils forces the magnets to move.
What is the formula of electric current?
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
When does the electric current flow?
An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
Is units of electric current a volt?
Electric current is measured in amps not voltsElectric voltage is measured in volts.
What is the relationship between voltage and electric current in the field of volt physics?
In the field of volt physics, voltage and electric current are directly related. Voltage is the force that pushes electric current through a circuit. The higher the voltage, the greater the potential for electric current to flow. This relationship is described by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), or I V/R.
What is is the formula of current?

What causes a current in an electric circuit?
Voltage causes current to flow in an electric circuit.
What is the difference in the current and voltage?
Current (amperes) is the rate of flow of electric charge, in coulombs per second. Voltage, on the other hand, is the electric potential of that charge, in joules per coulomb.Current and voltage are related to resistance by Ohm's Law, which states that voltage is equal to current times resistance.There is a tendency to misuse the term "current", and to apply it, for instance as "an electric current of 120 volts". This usage is incorrect. Current is current, and voltage is voltage, as noted above.
Is an electric voltage a varying electric current that reprsents information?
false
Who is resposible voltage or current for electric shock?
It is impossible to separate the two. The voltage determines the magnitude of the current, and the current causes the damage. So, they are both responsible for electric shock.
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 are the three elements of electricity?
The three basic elements of electricity are voltage, current, and resistance. Voltage is the force or pressure that drives the electrical current. Current is the flow of electric charge. Resistance is the opposition to the flow of electric current.
