Question

how to identify a wheatstone bridge in a circuit?

Answer 1

Answer:

When balanced, the Wheatstone bridge can be analysed simply as two series strings in parallel. In our tutorial about Resistors in Series, we saw that each resistor within the series chain produces an IR drop, or voltage drop across itself as a consequence of the current flowing through it as defined by Ohms Law.

$\Large{\textsf{\pink{\underline{\underline{ANSWER}}}}}$

★ Wheatstone bridge will always include five resistive element or 4 resistive elements and a galvanometer in a circuit .

★ The four resistance will appear to be parallel. So just check ratio .

★ If P,Q,R& S are Resistance then if -

• P/Q = R/S

★ Then it's a Wheatstone bridge circuit.
