Why a wheatstone circuit is called a bridge?
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
Should the ohmmeter be connected to the circuit while the power is being applied or only when the circuit is turned off?
Turn off the supply before using the ohmmeter,it will damaged your ohmmeter when supply is present.
State 3 functions of wheatstone bridge?
Wheatstone bridge is used to calculate the resistance of unknown resistor in the circuit.
Signal conditioning circuit of potentiometer?
you can use an impedence converter or a voltage follower
Is an ohmmeter connected in series or parallel?
You almost NEVER do. 1) The circuit should be off and/or disconnected when using an ohmmeter. 2) It should be in parallel with the component as far as the rest of the circuit is concerned, but alone in series with the device its measuring.
What is the difference between Wheatstone bridge and meter bridge?
WHEATSTONE BRIDGE : A wheatstone bridge is used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown compound.Its operation is similar to the original potentiometer. METER BRIDGE : A uniform resistance wire 1 meter in length, mounted above a scale marked in millimeters, with terminals added to make the device usable as either part of a wheatstone bridge or of a potentiometer.
Why a wheatstone circuit is called a bridge?
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
What is the configuration of the ohmmeter?
An ohmmeter is connected in parallel to a resistor. Be sure that there is no power in the circuit when testing.
Should the ohmmeter be connected to the circuit while the power is being applied or only when the circuit is turned off?
Turn off the supply before using the ohmmeter,it will damaged your ohmmeter when supply is present.
What if a ohmmeter reads infinity?
You have an open circuit.
What did Sir Charles Wheatstone invent?
A type of electrical circuit.
What meter must NEVER be connected to a circuit when the circuit power is turned on?
An Ohmmeter.
What is a Wheatstone?
The wheatstone bridge is an instrument used to measure electrical resistance by means of balancing a bridge circuit. The bridge circuit contains two legs, one of which contains the unknown resistance. Variations in wheatstone bridge can be employed to measure inductance, capacitance, and impedance also.

Who developed an electrical circuit invented by Samuel hunter Christie?
wheatstone
What step is unique to connecting an ohmmeter in the circuit?
check the circuit with a voltmeter to make sure the circuit is not powered
