Question

a potential diffrence of 4v is applied to 2 resistors; 2 ohm and 6 ohm in series. calculate

1)combined resistance

2)current flowing

3) potential diffrence across 6 ohm resistor

Answer 1

1 .AS BOTH ARE IN SERIES USE FORMULA OF SERIES CONNECTION

R= 2+6 OHM
8 OHM

2> CURRENT FLOWING (I ) = $\frac{V}{R}=\frac{4}{8}=0.5AMPERE.$

3> POTENTIAL DIFFERENCE ACROSS 6 OHM RESISTOR
$$\begin{gathered} V=I\times R \\ =0.5\times 6(ASBOTHRESISTORAREINSERIESTHATSWHYSAMECURRENTISFLOWING) \\ =3VOLT \end{gathered}$$
