Resistors are rated in ohms for their resistance value and in watts for the power they are capable of handling. They are not rated in volts or current.

Power delivered by 10ohms resistor and 25volt?

The power dissipated by a resistor is E2/R .If the "25volt" is the potential difference (voltage) between the ends ofthe resistor, then the resistor dissipatesE2/R = (25)2/10 = 62.5 watts .That's quite a fair amount of power ... more than you could expect to dissipatefrom a typical carbon composition resistor. This particular resistor is somethinglike a heating coil in a toaster or a large acquarium, for example.


How does current change through a resistor?

When an electric current flows through a resistor, the resistor resists the flow of the current, causing a decrease in the current. This decrease in current is proportional to the resistance of the resistor, as described by Ohm's Law.


Does current flow through a resistor, or does it flow across a resistor?

Current flows through a resistor, not across it.


A can be used to reduce the current in a circuit?

A resistor.


How does a resistor affect the flow of electricity in a circuit: does a resistor reduce voltage or current?

A resistor affects the flow of electricity in a circuit by reducing the current that flows through it. This reduction in current leads to a decrease in voltage across the resistor.


Is current is drop when it flowing through the resistor?

Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.


What is a ballast resistor?

A ballast resistor is an electrical resistor whose resistance varies with the current passing through it, thus maintaining a constant current.


Basic concept of resistor?

resistor is to resists the flow of current


What is the current drop across the resistor?

The correct question is what is the voltage drop across a resistor or the current flowing through the resistor using Ohm's Law where Voltage = Current x Resistance


Does a resistor reduce current or voltage in an electrical circuit?

A resistor reduces the flow of current in an electrical circuit, which in turn affects the voltage across the resistor.


Which is the Direction of the current in resistor?

A resistor is bi-directional meaning current can flow in either direction. Current flows from positive to negative.


How do you find power generated in a resistor?

The power generated in a resistor is converted into heat. and that can be power which is converted into heat is the product of the voltage across the resistor and, current passing through the resistor. or the product of square of the current and the resistance offered by the resistor.
