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.

What do you measure with electric current?
Electric current is typically measured in amperes (A), which is the flow of electric charge through a specific point in a circuit over time. This measurement helps determine the amount of electricity being transferred and the rate at which it is flowing in a circuit.
An electric iron is marked 240 voltagen 1200 w calculate the current flow through the electric iron?
To calculate current flow, use the formula: Current (I) = Power (P) / Voltage (V). Substituting the given values, the current flowing through the electric iron would be I = 1200W / 240V = 5A.
What is a galvanometer called when calibrated to read current?
A galvanometer calibrated to read current is called an ammeter. It is used to measure the flow of electric current in a circuit.
What happens if you placed an insulator in an electric field?
An insulator does not conduct electricity, so it will not allow the flow of electric current through it. When placed in an electric field, the insulator will become polarized, but it will not allow the movement of charges like a conductor would.
What do you nedd to produce a continuous path of electric current?
To create a continuous path for electric current, you need a closed circuit that includes a power source (such as a battery or generator), conductive materials for the current to flow through (such as wires), and a load (such as a light bulb or motor) to utilize the electrical energy. When these components are connected in a loop, the electric current can flow continuously.
What is the need of lamination in transformer?
The laminated plates prevent eddy currents from forming and thus creating unwanted magnetic flux which would counter the flux needed to induce the electric current in the secondary coil
Is arc welding an example of electric current?
No, an example of an electric current would be using a battery to light a lightbulb.
What would you expect to conduct an electric current?
the metal
Would increasing the resistance increase electric current?
no
What charge is an electric current?
Electric current is both positive and negative. If there were only one of those it would be an open circuit and it would not work. The particles would be able to flow one way but not the other.
Which instrument would measure an electric current?
A voltmeter or a multi-meter.
As electric generatar produce electric current due to magnetic induction than why current don't produce in electric motor as magnetic induction should also occur in electric motor?
I will attempt to answer the question I think your asking: 'If an electric generator produces an electric current due to magnetic induction, then why isn't a current produced via the same mechanism in an electric motor?' The answer to the best of my understanding is that it is, or at least, it would be. The reason is that in a generator a conducting wire is rotated in a magnetic field and this induces a current as each charged particle experiences a force as determined by F=q(vxB) [this is the vector form of the equation using the vector product] or F=Bqv if you are unfamiliar with vectors. As this causes electrons to move this manifests itself as an alternating current in a wire. Conversely in a motor and alternating current is passed through a magnetic field in a coil of wire, this time the wire now experiences a force F determined by F=I(lxB). This produces a torque on the centre of the motor and it is this torque that drives the motor. However if you were to rotate the coil of the motor externally without supplying a current to it then the reverse process would take place. This would induce an AC current in the motor which would now function as a generator. As a aside if this current was then driven through the generator it would then rotate exactly as the motor did.
What type of magnetic field will produce an electric current in a wire?
A current carrying wire has a magnetic field around it but no electric field.There will be electric field around a body only if it has static electricity.In this wire, charges(electrons) are moving.The number of charges entering is equal to number of charges leaving the conductor.So it remains neutral.A neutral body cannot have an electric field around it. ACTUALLY, there IS also an electric field. A current is made up of moving charges, and all charges (moving or static) create an electric field. Materials that have a neutral charge are not good conductors and therefore would not have a current going through them in the first place.
Will lightning start your car?
It would have to induce the right dc current in the starter motor and energise the ignition at the same time, so unlikely
Does a generator work in space?
No, a generator relies on the movement of a coil within a magnetic field to generate electricity, which requires gravity to function properly. In the absence of gravity, there would be no movement to induce an electric current.
How much current should be given to mice in Electric Shock experiment?
The amount of current that should be given to mice in Electric Shock experiments would depend on what is being tested
What do you measure with electric current?
Electric current is typically measured in amperes (A), which is the flow of electric charge through a specific point in a circuit over time. This measurement helps determine the amount of electricity being transferred and the rate at which it is flowing in a circuit.
