TBQ - Resistors in parallel — task. Physics CBSE Live product, Class 10 (2026-27).

Calculate the correct values:

In the circuit diagram given in figure, suppose the resistors \(R_1\), \(R_2\) and \(R_3\) have the values \(2\ Ω\), \(4\ Ω\), \(8\ Ω\), respectively, which have been connected to a battery of \(12\ V\).

Circuit diagram

Calculate

a. The current through each resistor
b. The total current in the circuit, and
c. The total circuit resistance

a. The current through each resistor is calculated by the formula

i = \frac{i}{i}

Current through \(R_1\) \(=\) \(A\)

Current through \(R_2\) \(=\) \(A\)

Current through \(R_3\) \(=\) \(A\)

b.Total current in the circuit,

i = i_{i} + i_{i} + i_{i}

On substituting the known current values, we get \(A\).

c.Total resistance in the circuit,

\frac{1}{R_{P}} = \frac{1}{R_{i}} + \frac{1}{R_{i}} + \frac{1}{R_{i}}

On substituting the known values, we get

\begin{array}{l} \frac{1}{R_{P}} = i \\ R_{P} = i Ω \end{array}

[Note: Enter the answer upto 2 decimal places]
