A resistor affects the flow of electric current in a circuit by providing resistance, which limits the amount of current that can pass through it. This control of current helps protect components from damage and allows for the adjustment of voltage across various parts of the circuit. Additionally, resistors can be used to divide voltages, generate heat, and create specific voltage levels necessary for the proper functioning of electronic devices.
A bad heater blower motor resistor would effect one or more blower speeds other than high.
Connecting an ammeter in series with a resistor in a circuit will not affect the current through the resistor. The ammeter measures the current passing through it, so it becomes part of the circuit and simply measures the current flowing through the resistor without changing it.
adding resistors to a string will have the effect of decreasing each resistor voltage drop.
RMS value is defined as "The amount of ac supply required to make same heat effect in resistor , which is made by dc current, in that resistor"
An emitter resistor in a common emitter circuit will cause the stage to experience the effects of degenerative feedback if it is unbypassed. The degenerative feedback reduces gain. This is probably the primary effect in the described circuit.
When the heater resistor goes, your climate control fans will only work on the fourth setting. You can get a new resistor from any Ford Lincoln Mercury dealer, though they may have to order one.
A resistor is a resistor. Plain and simple. By Ohm's Law, resistance in ohms is voltage in volts divided by current in amperes. The difference lies in application, not in the resistor itself. A normal resistor will introduce a voltage drop or current that makes some effect in the circuit, based on some design criteria. A bleeder resistor, on the other hand does not really affect the circuit - it is only there to "bleed off", or discharge, capacitors when the power is turned off. Consequently, a bleeder resistor will typically have a higher resistance than a normal resistor but, again, the issue is circuit design, not the resistor itself.
It provide sufficient biasing to the transistor. ANSWER: It purpose is to provide bias and limiting gain.
Of course. A good voltmeter can be applied across anything, since its impedance is high and its presence has no effect on the operation of the circuit. When it's connected across a variable resistor, the voltmeter most likely reveals a changing voltage as the resistor is varied.
Of course it depends entirely on the ohm's resistance of the resistor. The higher the resistance, the lower the comparison to a short circuit.
It means the maximum power each one is capable of dissipating. The power dissipated by a resistor is (current through it)2 x (its resistance). If you exceed the power rating of a resistor, it will overheat, and that always increases its resistace value, at least for as long as it remains hot. If you take it to the extreme, the resistor can melt, smoke, crack, explode, etc. The power rating of a resistor has no direct effect on its resistance value.
A very very tiny amount of the current that would normally flow through the resistor instead flows through the voltmeter, allowing it to make its measurement. For most purposes this very very tiny amount of current can be completely ignored.
