volts.
AA zinc and alkaline batteries normally provide 1.5 Volts when they are new. The voltage will drop as the battery discharges. Rechargeable batteries using NiCad or NiMH technology deliver 1.2 Volts when fully charged. Again, the voltage will drop as they discharge. It is this small voltage difference that can make rechargeable batteries less effective for some voltage sensitive applications,
The voltage drop depends on the current through the cable.For DC current in cable of 16 mm diameter, at 68° F, the voltage drop is(0.00857) x (current, Amperes) volts.
Each voltage has a range and devices rated in that range will all work . The 110 to 120 volts is one range of voltages. The 220 to 240 is another range of voltages. The reason there is a range of voltages is to help the utility company out. They are mandated to keep the voltages within a + or - 5% range of a set voltage. Because there are loads coming on line and loads dropping off line the voltage fluctuates. Using a base voltage of 115 and 230 volts means that the voltage can rise by 115 +5% = 121 volts and drop by 115 - 5% = 109 volts. In the 230 volt range the voltage can rise by 230 + 5% = 241 and drop by 230 - 5% = 219 volts. As you see they are still in the usable voltage ranges.
120 Volts and 115 Volts refer to the same thing in the US. Residential electricity is provided at 120 Volts from the utility. High current devices such as motors are often rated at less than the supplied voltage (such as 115 Volts) because it is expected that there is a small amount of voltage drop in the circuit feeding them. The National Electric Code allows a 5% drop in voltage from the electric service so a 5 Volt drop from 120 Volts is OK.
volts.
The voltage drop across an LED varies, but is typically around 2 volts.
the voltage drop means whenever the conductor passing through the supply voltage, according to the resistivity property to reduces the some amount of voltage that drop is known as voltage drop for example the resistance is used to drop the voltage to the circuit.............................................
What is the voltage drop running through resistor one
forward bias 0 volts, reverse bias infinity volts.
there is 120V across the circuit.
6 AWG will handle 50 amps with a voltage drop of about 4 volts. If you go to 4 AWG and limit to 50 amps your voltage drop will be 2.5 volts.
A regulator loses some voltage in regulating its output, known as the dropout voltage. So the input voltage must be at least the output volts plus the dropout volts. If the input voltage is too low, the output will drop out of regulation.
AA zinc and alkaline batteries normally provide 1.5 Volts when they are new. The voltage will drop as the battery discharges. Rechargeable batteries using NiCad or NiMH technology deliver 1.2 Volts when fully charged. Again, the voltage will drop as they discharge. It is this small voltage difference that can make rechargeable batteries less effective for some voltage sensitive applications,
It is generally accepted to be approximately .7 volts.
12 volts
If there is nothing else in the circuit, then the voltage drop across the resistor will be the full supply voltage of 5 volts. The size of the resistor does not matter in this case - it will always be 5 volts.
