Ω, 20 Ω, 30 Ω and 40 Ω. If a voltage of 12 V is applied across the bridge, what is the voltage drop across the 30 Ω resistor?
To solve this problem, we need to use the formula for the voltage drop across a resistor in a Wheatstone bridge:
V = (R2 / (R1 + R2)) * Vin - (R4 / (R3 + R4)) * Vin
where V is the voltage drop across the resistor we are interested in, R1, R2, R3 and R4 are the resistances in the Wheatstone bridge, Vin is the voltage applied across the bridge.
Plugging in the values we have:
V = (20 / (10 + 20)) * 12 - (40 / (30 + 40)) * 12
V = 0.4 * 12 - 0.57 * 12
V = 4.8 - 6.84
V = -2.04 V
Therefore, the voltage drop across the 30 Ω resistor is -2.04 V. Note that the negative sign indicates that the voltage drop is in the opposite direction of the current flow.
