Can a resistor be installed backwards?
Resistors can be installed in any direction in a circuit. It doesn't matter in which direction you are installing a resistor. Resistor will resist the current in both sides of the connection. You can also apply capacitor in any direction for alternating current. Where as if you are concerned with direct current, a direction is needed to apply the connection
What is the main difference in operation between diodes and resistors?
A diode is an electronic component which only allows the current to pass through it in one direction. This is useful in many aplications, such as preventing current to flow in the wrong direction in a circuit. A resistor is also an electronic component, but instead of preventing the current from moving in a certain direction the resistor creates an electrical resistance which will effect the current passing through it. The larger the resistance of the resistor, which is measured in Ohm, the greater the effect it will have on the current.
How are the plus and minus voltage signs determined for resistors?
Resistors have no polarity. The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).
An electronic device that limits the amount of current that can flow through it?
Not in normal circumstances. A diode is an electonic device that allows current to flow freely in only one direction.
A can be used to reduce the current in a circuit?
A 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
What do you call something that cannot pass electricity?
Diode's are restrictive to one direction of current only. A resistor will limit the amount of current in a circuit.
Current divider rule?
Ix = IT(Rp/Rx+Rp) where Ix is the current you are trying to find, IT is the total current, Rx is the resistor in question, Rp is/are the resistor(s) in parallel with the resistor in question.
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.
