Total Current in Wheatstone Bridge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Current (total) Op = (Voltage (Thevenin))/(Resistance (Thevenin)+Galvanometer Resistance)
I_op = (E_th)/(R_th+R_g)
This formula uses 4 Variables

Variables Used

Current (total) Op - (Measured in Ampere) - Current (total) Op is the total amount of current flowing through the circuit with the load.
Voltage (Thevenin) - (Measured in Volt) - Voltage (Thevenin) is the total effective voltage in the Thevenin equivalent circuit of the unbalanced Wheatstone bridge.
Resistance (Thevenin) - (Measured in Ohm) - Resistance (Thevenin) is the total Thevenin resistance for an unbalanced Wheatstone bridge.
Galvanometer Resistance - (Measured in Ohm) - Galvanometer Resistance is the value of internal resistance of the galvanometer connected across arm BD (ABCD is labelled clockwise, with A being labelled at the top).

STEP 1: Convert Input(s) to Base Unit

Voltage (Thevenin): 5.35 Volt --> 5.35 Volt No Conversion Required
Resistance (Thevenin): 40 Ohm --> 40 Ohm No Conversion Required
Galvanometer Resistance: 12.4 Ohm --> 12.4 Ohm No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_op = (E_th)/(R_th+R_g) --> (5.35)/(40+12.4)

Evaluating ... ...

I_op = 0.102099236641221

STEP 3: Convert Result to Output's Unit

0.102099236641221 Ampere --> No Conversion Required

FINAL ANSWER

0.102099236641221 ≈ 0.102099 Ampere <-- Current (total) Op
