If $V_{A} = 2 V$ calculate current flowing through the circuit and calculate $V_{B}$ and $V_{C}$ ?

Open in App

Solution

Equivalent resistance of the circuit $= R = R_{A} + R_{B} + R_{C} = 2 + 2 + 6 = 10 Ω$

Now, current in the circuit $= I = \frac{V}{R} = \frac{10}{10} = 1 A$

$V_{B} = I R_{B} = 2 V$
And, $V_{C} = I R_{C} = 6 V$
