Question

Q86. In the arrangement shown in figure, the current through 5 ohm resistor is
a 2A
b zero
c 12/7 A
d 1A ​

Answer 1

$\huge{\underline{\tt{\red{Answer}}}}$

a) 2A

$\huge{\underline{\sf{\blue{Solution-}}}}$

⭐Given⭐= 5 ohm = resistance

        = Two cells

        = Voltage = 12V

⭐Find⭐ = Current {A}

⭐Solution⭐=

Total resistance of the circuit

$R_t = 5+ \dfrac{2\times 2}{2+2}$

    $= 6 \Omega$

Current = $\dfrac{V}{R_t} = \dfrac{12}{6} = 2 A$
