What is the amount of electric energy supplied if the current and voltage are doubled?
Energy is measured in the SI unit Joule. One definition of a Joule is one ampere passing through a resistance of one ohm for one second. Thus doubling the electrical current (amperes/amps) passing through a resistance of one ohm for one second will double the energy. As for voltage, given that voltage (volts) = current (amps) times resistance (ohms) then, assuming a constant resistance, the voltage will double if the current doubles. Thus doubling the voltage (and therefore the current) passing through a resistance of one ohm for one second will double the energy (joules).
What else can I help you with?
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
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.
What controls the flow of electric current?
The flow of electric current is controlled by the voltage applied to a circuit. Voltage creates an electric field that pushes charged particles (electrons) through a conductor, allowing current to flow. The resistance in the circuit also affects the flow of current, as it determines how much opposition the current encounters.
Does voltage divided by watts equal the current?
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
Can a magnet stop an electric current?
A magnet cannot stop an electric current, but it can influence the flow of the current. Moving a magnet near a wire carrying an electric current can induce a voltage in the wire, which can affect the behavior of the current.
What do you understand by electric current?
electric current is the flow of electrons due to external energy (emf) supplied by the voltage source.
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)
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
Voltage across resistor is doubled the current is?
Ohm's law states that the voltage across a resistor is the product of the current times the Resistance or V=I x R (I times R). V is Voltage, R is Resistance, and I is Current or Amperage. So if the Voltage is doubled and Resistance stays the same, the Current will be doubled.
If you doubled the number of coils and doubled the voltage what would be the increase in magnetic strength?
well if you doubled the coils it would be pie times the amount of voltage in the current squared
What happens to the current when the voltage is doubled and the resistance is constant?
If the voltage is doubled and the resistance is constant, Ohm's Law states that the current will also double. This is because the relationship between voltage, current, and resistance is linear, and increasing the voltage will directly increase the current flow.
What is the electrical voltage are supplied by the power supply on your system?
The electric voltage are energy to my system.
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
If the resistance in a circuit is doubled while the voltage remains constant the current does what?
If resistance is doubled in a circuit with constant voltage, Ohm's Law (V=IR) states that current (I) would be halved since the voltage is constant. This is because the relationship between resistance and current is inversely proportional.
Does the amperage double when you double both the current and the voltage in a circuit?
No, the amperage does not necessarily double when both the current and voltage are doubled. Amperage (current) is determined by Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). If both voltage and current are doubled while resistance remains constant, the new current would actually be four times the original current, not just double.
How the current are related to the power supplied by the source?
Power (watts) is voltage times current.
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).
