There is a total of 500mA of current into five parallel resisters the currents through four of the resistors are 50mA 150mA25mA and 25mAand 100mA what is the current through the fifth resister?
150 mA is.

Can electricity kill you?
At levels of current flow exceeding 1/10 of an amp or 100 milliamps, the heart stops. This is called fibrillation. A person may survive an electrocution if his or her heart can be started again. This is why CPR is such an important skill in the electrical industry
What is 50mA equal to?
50 micro ampheres
Assume a device draws 50ma of current and 150vdc across it what is its resistance?
Ohm's law: Voltage = Current times Resistance Solve: Resistance = Voltage divided by Current So, a device drawing 50ma with 150V has a resistance of 150 / 0.05, or 3000 ohms. p.s. Since power is volts times amps, that device is dissipating 7.5 watts.
What power source is needed for 26 small 12volt incandescent 50ma lights?
They could be run in parallel from a 12 v 1.5 amp power supply.

What can be pulling to much power from my van and not returing it to my battery?
Its called a parasitic draw. Any electrical component in the vehicle could cause it. To test for a draw, pull the negative battery cable and use a meter to measure amperage between the battery terminal and cable. The reading should usually be below 50mA or <.050 amps.
What is the maximum voltage to normal type LED with out using resistor?
This varies depending on the color. Try driving them with a current source instead. About 5mA to 50mA should work on any LED. Using a voltage source will blow some colors, and not light other colors at all. Of course a current source is likely to be more expensive than a series resistor.
Can you use a 12v dc 1.6a power supply on devices that require 12v dc 50Ma?
You have to be careful because many small power supplies are poorly regulated, which means that they supply excessive voltage when there is a small current load. A 12 v supply might supply 16-17 v when the load is only 50 mA so unless you can check this it's best not to use it.
How many lumens does an 18 watt CFL give off?
Currently maximum LED luminous efficiency is about 114 lumens/W, measured at 50mA. Average luminous efficiency is about 104 lumens/W. Ordinary LED light effect is about 60 lumens / W. 18W is about 130 lumens is about 1080 lumens.
When two terminals of 4.5 Voltage battery are connected by 100 meters long wire. the current in the wire is 50mA what will be the current from the battery when the wire is shortened 50 meters?
-- The resistance of the wire is proportional to its length. -- When the length is reduced by 1/2 , the resistance is also reduced by 1/2 . -- Reducing the resistance across the battery by 1/2 causes the current to double. -- The new current is 100 mA. (Assumes zero internal resistance in the battery, and that the 4.5 volts doesn't 'sag'.)
