A capacitor of capacitance `3muF` is first charged by connecting it across a 10 V battery by closing key `K_(1)`. Then it is allowed to get discharged through `2 Omega` and `4 Omega` resistors by closing the key `K_(2)`. The total energy dissipated in the `4 Omega` resistor is equal to

A capacitor of capacitance 3 mu F is first charged by connecting it across a 10 V battery by closing key K_(1) , then it is allowed to get discharged through 2 Omega and 4 Omega resistors by opening K_(1) and closing the key K_(2) . The total energy dissipated in the 2 Omega resistor is equal to

A current of 3 A flows through the 2 Omega resistor as shown in the circuit. The power dissipated in the 5 Omega resistor is

In given circuit initially switch S_(1) is closed for long time and then opened and now S_(2) is closed. The total energy dissipated in 4 Omega resistor is equal to :-

In an electrical circuit, two resistors of 2 Omega and 4 Omega respectively are connected in series to a 6 V battery. The heat dissipated by the 4 Omega resistor in 5 s will be :

A capacitor of capacitance 100(mu)F is connected across a battery of emf6.0V through a resistance of 20k(Omega) for 4.0s after the battery is disconnecting?
