Wheatstone bridge (balanced)
P/Q = R/S
Where: P = power (W) / pressure (Pa), Q = heat (J) / charge (C), R = range / radius / resistance, S = S
Solved example
Given: Q = 7, R = 5, S = 10
Find: P (power (W) / pressure (Pa))
- Formula: P/Q = R/S
- Rearranged for P: P = Q·R/S
- Substitute the values: P = 5·7/10
- Result: P = 3.5
Answer: P = 3.5
