Network Elements One Mark Questions A de circuit shown in figure has a voltage source V, a current source I and several Tesistors. A particular resistor R dissipates a power of 4 Watts when V alone is active. The same resistor R dissipates a power of 9Watts when I alone is active. The power dissipated by R when both sources are active will be (GATE - 93) Network 5] rs ra (a) 1W (b) 5W (©) 13W (d) 25W 01.
