Question

calculate the unknown resistance "RDC" in the Wheatstone bridge circuit,if PAB=400 ohms, QBC=200ohms and SAD=12ohms at balanced condition​

Answer 1

Given that PAB=400 ohms, QBC=200ohms and SAD=12ohms at balanced condition​

We need to find the unknown resistance.

What is resistance?

The obstruction to current flow in an electrical circuit is measured by resistance. The Greek letter omega () represents the unit of measurement for resistance, known as ohms. Georg Simon Ohm (1784–1854), a German physicist who investigated the connection between voltage, current, and resistance, is the name given to the unit of resistance.

Now PAB=400 ohms,

QBC=200ohms and

SAD=12ohms at the balanced condition​

Therefore, the resistance

$R=\frac{200 \times 12}{400}\\= 6 \ ohm$

Hence, the required resistance is 6 ohm.

Answer 2

Conclusion

What is resistance

Resistance measures the impediment to current passage in an electrical circuit. The Greek letter omega represents the ohm, which is a unit of resistance measurement. The unit of resistance is named after Georg Simon Ohm (1784-1854), a German scientist who studied the relationship between voltage, current, and resistance.

Now PAB=400 ohms,

QBC=200ohms and

SAD=12ohms at the balanced condition​

Therefore, the resistance

$R = \frac{200 \times 12}{400} \\= 6 omh$

Hence, the required resistance is 6 ohm.
