उत्तर
Given Data:
Three resistors (40 Ω, 20 Ω, and 10 Ω) are connected in a parallel combination across the points A and B.
Potential difference of the battery (V) = 12 V
Principle:
In a parallel circuit combination, the potential difference (voltage) across each individual branch remains completely identical and is equal to the total supply voltage of the source. Therefore, the voltage across the 20 Ω resistor is exactly 12 V.
Formula:
According to Ohm's Law, the electric current (I) flowing through a specific resistor is given by:
I = `V/R`
= `12/20`
= `3/5`
= 0.6 A
The electric current that passes through the 20 Ω resistor in the given circuit is 0.6 Amperes.
