What are the basic test instruments in electricity?
A "multimeter" to test resistances, voltages, amperages. An external "clamp" meter to measure high ac currents. A "mega" meter to test insulation.
Are all resistances in series connections the same?
No, all resistances in series connections are not the same. Different value resistances can be series together. The results of the resistances in series are always the same, they are additive.
Why rated current should flow in the secondary for short circuit?
The short-circuit test runs the rated current through the windings of the transformer to measure the copper-loss, or power lost in the winding resistances. Because the transformer is run at low voltage for this test, there is very little additional power loss in the iron core of the transformer.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
Modern electronic multimeter measures resistances by?
forcing a constant current and measuring the voltage across the unknown resistor.

How did Algeria's resistances to french rule differ from the east African's resistances to German rule?

How do you test a ignition module on 1992 Honda civic?
Many autopart stores have a machine to test it. The machines use a universal adapter to hook into the ignition control module. The ignition control module is in the distributor. If you mean the part that contains the ignition coil, when mine went bad I probed it with an ohmeter and then asked the parts store if I could test the resistances in a new coil before I bought it. Since the resistances of certain terminals weren't even close, I knew I had a bad coil.
What term remains the same across all the resistances in a parallel combination of resistances?
The voltage across the resistors will remain constant.
What are non ohmic resistances?

10 ohms 60 ohmsand 50 ohms are wired in series and connected to a 120-V battery What is the equivalent resistance for this circuit?
For a series circuit such as this, simply add the resistances to get the equivalent resistance.For a series circuit such as this, simply add the resistances to get the equivalent resistance.For a series circuit such as this, simply add the resistances to get the equivalent resistance.For a series circuit such as this, simply add the resistances to get the equivalent resistance.
What happens to the brightness of the light bulbs in a series with a heater?
They dim as the total resistance of series of resistances is the sum of the resistances; and current = V/R.
How does water resistance works?
how does water resistances work
What are the multiple resistance circuits?
a circuit with many resistances.
How can the Murray loop test be used for locating the phase to phase fault?
By using wheatstone bridge principle we can proceed to find the phase to phase fault's.i:e the wheatstone bridge is mainly used to find the resistances/inductance/capacitances.it is mainly consists of 4 resistances like this(<>)& having a galvanometer in centre&a battery is connected to it. when ever the current flowing through the galvanometer is zero by varying the one resistance,then the ratio of two resistances connected at one end is equal to other two resistances ratio.By using the same principle ,one phase is connected to known resistance and a good cable is shorted to the fault cable.and other resistane is connected to the good cable&a galvanometer is connected to it.by varying the resistances the galvanometer shows null reading.then bridge is balanced & by using bridge equation we can solve to find the distance where the error is located
What are the series circuit rules?
current is constant in the series circuit. The resistances of the components add up and the potential differences is divided propotionally over the components depending on their resistances.
