Question

In the given circuit calculate the power consumed in watts in the resistor of 2 Ω : 2

Numerical

Solution

Total Resistance = 1 Ω + 2 Ω = 3 Ω 

Total applied voltage (V) = 6V

Circuit Current (I) = `"V"/"R"`

= `(6"V")/(3 Ω)`

= 2A

Power Consumed across 2 ohm resistor

= I2R

= 22 × 2

= 8W
