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
Do you need to apply a load to see a voltage drop across a resistor?
You'll see a voltage drop across a resistor if current is flowing through it. It only has to be a part of a complete circuit, i.e. one in which current is flowing.
For voltage drop calculation you must use the current of the circuit breaker or the normal currents?
For voltage drop calculation you must use the current of the load and the distance of the load from the supply source. The circuit breaker is then used to limit the current to the rating of the wire that feeds the load.
How do you calculate the maximum weight of a swing from the working load weight?
If a swing has a working load of 300 pounds and the rotation hook has a working load of 1000 pounds, what is the maximum weight of a person that would be allowed on the swing?
Why does the terminal voltage decreases as the load current increases?
A: That will happen anytime the voltage source is not able to provide the power needed for the load. If the load exceed the power available from the source the voltage will be reduced as IR drop from the source
What would cause high voltage drop readings?
High resistance on the feeder to the load will cause voltage drop at the load end of the circuit. If this is happening, do the calculations for voltage drop, using the amperage of the load, voltage of the load, the size of the wire feeding the load and the distance from the distribution panel to the load.
Where does a river drop the load?

Can you hook up a 4ohms sub and a 2ohms sub to the same amplifier?
ONLY if your amp can pull a 2 ohm load! Which is vary few but your more expensive amp can pull 1/2 ohm load
Do you need to hook up a load wire?
The load is essentially what consumes electrons. For example a load on a light circuit would be a bulb. Therefore, if you don't hook up a load you aren't doing anything. It is like turning on a light switch without a bulb. It may give you some minor exercise, but it doesn't do anything useful.
Why there is a voltage drop during load shedding?
poor regulation
What amount of voltage that is used by each load depends on the?
drop
What size wire needed with a 100 amp load 250 feet away?
The question is one of voltage loss. The goal is to have enough ampacity in the selected conductors to run the maximum load with only 3 percent voltage drop, caused by the resistance inherent in the wires. Plug your numbers into a voltage drop calculator online and see what pops out. At 120 volts you would get 3.1 percent drop using 3/0 wire. At 240 volts you could drop down three sizes to #1 AWG for 3.1 percent at max load, or 1/0 size for 2.5 percent drop at max load. Assuming copper wire at normal conditions of temperature.
What are the differences between emf and voltage drop?
emf and voltageAnswerElectromotive force is the potential difference created by a source, such as a battery or generator, when it is not connected to a load -in other words, on 'open circuit'.Voltage drop is the potential difference across a load, such as a resistor, which causes current to flow through that load.A voltage drop occurs, internally, in batteries and generators, when they are supplying a load. The battery or generator's terminal voltage, when supplying a load, is its e.m.f. less its internal voltage drop.
Do you need to apply a load to see a voltage drop across a resistor?
You'll see a voltage drop across a resistor if current is flowing through it. It only has to be a part of a complete circuit, i.e. one in which current is flowing.
Why the output voltage drop when the load current is increase?
As the load current increases the losses in the circuit increases (I2R loss) and speed of the generator decreases so the voltage falls a little. and this voltage fall can be adjusted by increasing the speed of the generator and Iron losses are taken as constant losses.
What is point load of a crane?
Point loads occur when relatively high weights are concentrated on a small bearing area. So; point load on a crane with hooks is a load that is not centered. If you try to pick something up with the end of the crane hook, the load is not centered and would be "point loaded". This type of load will stress the crane cables. When the load falls off the hook-point, the crane cables react - and can break strands of the cable. The crane cable consists of an inner cable and outer cables - so as a load is placed on the cable, it stretches. If this load suddenly shifts or falls, the cables retract quickly and can break. This is dangerous, as you may not notice the inner cable has broke (could be a small bulge in the cable). Using the crane with a broken cable can cause it to fail and drop the load. A stable load is one in which the center of gravity of the load is directly below the main hook and below the lowest point of attachment of the slings. The center of gravity of an object is that point at which the object will balance. The entire weight may be considered as concentrated at this point. A suspended object will always move so that the center of gravity is below the point of support. In order to make a level or stable lift, the crane or hook block must be directly above this point. Thus a load which is slung above and through the center of gravity will be stable and will not tend to topple or slide out of the slings.
