The schematic diagram is shown below

Current Flowing Through 20Ω resistor

Current (I) = \(\frac{Voltage (V)}{Resistance (R)}\)

⇒ Current = \(\frac{10}{20}=\frac12\) = 0.5 A

Hence the current flowing is 0.5 Ampere.

Power consumed by the 30 Ω resistor

Power = Voltage × current.

Given Voltage = 10V; current = 0.5A

⇒ Power = 10 × 0.5 = 5W

**Hence power consumed by 30 Ω resistor is 5W.**
