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.
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.
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.
Current flows through a resistor, not across it.
A resistor.
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.
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.
A ballast resistor is an electrical resistor whose resistance varies with the current passing through it, thus maintaining a constant current.
resistor is to resists the flow of current
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
A resistor reduces the flow of current in an electrical circuit, which in turn affects the voltage across the resistor.
A resistor is bi-directional meaning current can flow in either direction. Current flows from positive to negative.
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.
