Calculate the potential drop across r2

WebThe total voltage across the resistors is given by V = R1+R2. When resistors are connected across each other in a circuit, they are said to be connected in parallel combination. Consider two resistors, namely R1 and R2, connected in parallel combinations. The total resistance across the voltage is given by 1/R = 1/R1+1/R2. WebAssume the voltage drop across resistor 1 is V1, across resistor 2 is V2, and across resistor 3 is V3. Write doZn the e[pression for currents in this circuit. Assume the current through R1 is I1, current through R2 is I2, and through R3 is I3. Calculate the value of current floZing across each resistor.
