Does voltage flow across or through a resistor?
No. If a voltage is applied across a resistor, a current flows through it.
What is forward current?
This is the current that flows under the application of a forward voltage. For eg. the dc forward current for an LED may be 30 mA when a forward voltage of 2.0V is applied.
When a voltage is applied across a diode and current flows we say the diode is what?
One description would be forward biased.
What happens to the applied voltage when a change in circuit resistance occurs?
When a dc supply is connected to a resistor, current flows. The current in amps is equal to the supply voltage divided by the resistance in ohms. The power used is the voltage times the current, and that appears as heat in the resistor, which might become hot to touch.
What limits the current that flows through a circuit for a particular appllied DC voltage?
The voltage applied and the resistance across it.
Why the current flows from the S pole to N pole in the interior of the magnet?
The flow of current has nothing to do with magnetism. It will flow in any direction you want, depending on the applied voltage.
What is the current that flows through an unloaded voltage divider?
The Bleeder current.
What are the 2 kind of circuit?
The two basic circuit types are series circuits and parallel circuits. In a series circuit, all the current flows through each component, and each one drops some of the applied voltage. In a parallel circuit, the applied voltage is dropped across each parallel component and current "splits" so some flows through each component.
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.
How do you create current from Voltage?
Electric current is what flows when the voltage is applied across a resistance. Electrons flow from the negative end to the positive end. Strictly, if everything was at the same voltage no current will flow because there is no distinction, positive or negative between the ends. So people often talk more accurately of voltage difference, or potential difference.
What is the function of enhancement mosfet?
An enhancement MOSFET doesn't conduct current across the drain to source unless a voltage is applied to the gate. When sufficient voltage is applied to the gate of the transistor, currents flows from drain to source. A MOSFET acts as a switch or amplifier in a circuit.
What is power factor of resistor?
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
