In the figure given, the electric current flowing through the 5 k Ω resistor is 'x' mA. The value of x to the nearest integer is ____________. Numerical answer type. Work it out, then open the answer.

Answer: 3. Three 3 kΩ in parallel = 1 kΩ. Total R = 5 + 1 + 1 (internal) = 7 kΩ I = (21)/(7 kΩ) = 3 mA, the full current passes through the 5 kΩ resistor. x = 3

Kirchhoff's Laws & Measuring Instruments

In the figure given, the electric current flowing through the 5 k $\Omega$ resistor is 'x' mA.

The value of x to the nearest integer is ____________.

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 3

Three $3\ \text{k}\Omega$ in parallel $= 1\ \text{k}\Omega$ .
Total $R = 5 + 1 + 1\ (\text{internal}) = 7\ \text{k}\Omega$
$I = \dfrac{21}{7\ \text{k}\Omega} = 3\text{ mA}$ , the full current passes through the $5\ \text{k}\Omega$ resistor.
$x = 3$
