What is the voltage across the first ohm resistor?
if R4 is the only resistor (the load), then the drop would be the same as the energy source
Does the change in the load resistor change the current in the arms of an unbalanced bridge?
No
Difine what is fixed tapped resistor?
This is usually a resistance wire wound resistor that has a physical connection on the body of the resistor called a tap. It about the same as tapping a water line to attached a hose line to your icemaker.
What size resistor needed to drop 3 volts dc to 2.5 volts dc?
You will need to take the resistance of the load into account if you are going to design a voltage divider. The resistance of the load can completely change the voltage ratio of a voltage divider if not factored into the calculation. you can measure or read R(load), then R(needed) = 0.8 R(load)
What is the purpose of a resistor applied to the base of a transistor?
Any system you design will have an input and an output. The output will connect to the input of another system which will load it, so when you are designing any system you have to consider how loading it will effect the circuit performance.
What is the meaning of load resistance?
"Load resistor" is a discriptor, not a value. Any resistor can be a load resistor if it is the proper value and power for your application. So if you want a load resistor by itself, that makes no sense. A load resistor is a resistor selected for a specific purpose. For example, it you want to put a load on an audio amplifier made to drive an 8 ohm speaker to 50 watts, then your load resistor would be a 8 ohm 50 watt resistor. If you want a load resistor to terminate a 50 ohm line, you would need a 50 ohm resistor, although in this case, you probably want one that is part of a co-ax connector. A load resistor for an op-amp output is typically 2k, since most op-amps are rated for 10 volts at 5 mA. Etc, etc.
How do you install a resistor in an DC circuit?
It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load. To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow. To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.
What is the purpose of a resistor connected in the series with the load resistor?
Divide the voltage
What is RL load?
It is load resistance RL. It can be any device that can act as a load at the output end. Example : A resistor
If you doubled the load resistor in a wheatstone bridge. the load current would not be half as much Why not?
Because by increasing the load resistance, the total circuit resistance is reduced. This means with less resistance, there is more current drawn from the source. Doubling the size of a load resistor increases the load current.
What is the end of line resistor used for in fire alarm circuits?
An End of Line resistor is used to create a small constant load in a protective zone or loop. The control panel monitors the current in the loop to detect if the wires have been cut open, or shorted, both of which would be either a "trouble" or "alarm" indication.

Does the change in the load resistor change the current in the arms of an unbalanced bridge?
No
What is a load line of transistor?
what is load line of transistor what is load line of transistor
Symbol for resistor?
-------------[_________]-------------- and put a line on the top of the box
Difference between dc load line and ac load line?
well the difference mainly exists in the method of finding them , these are :-1. in finding DC load line :-open all AC sourcesopen all the capacitors2. for AC load line:-open all the Dc sourcesshort all the capacitors.
Is an on-load tap changer considered as a resistor?
No. All a tap changer (whether 'off-load' or 'on-load') does is to make minor changes to the turns-ratio of a transformer.
