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.
