The Wheatstone bridge is a circuit used to measure unknown resistances. The bridge in the figure is balanced - no current flows through the galvanometer. What is the unknown resistance $R_{x} ?$ [Hint: What is the potential difference between points $A$ and $B ?]$
In the circuit shown, the galvanometer shows zero current. The value of resistance R is : A) 1 WB) 2 WC) 4 WD) 9 W
Pritesh R.
Consider the circuit shown in the figure. Take R1=R, R2=2R and R3=R. Find the magnitude of the current passing through the resistor R3 in terms of V/R . Express your answer using one decimal place.
