21.
Three resistances of 15 Ω, 10 Ω and 3 Ω are connected in parallel. The overall resistance is
Answer: Option
Explanation:
For resistances is parallel, overall resistance is less than the smallest resistance.
22.
In figure, the switch is closed at t = 0. At t = 0+ The value of current supplied by battery is
Answer: Option
Explanation:
At t = 0, current in R-L branch is zero.
23.
In the circuit shown in the figure the power dissipated in 30 Ω resistor will be maximum if the value of R is
Answer: Option
Explanation:
If R = 0, it will be act a short circuit, 16 Ω Resistor will not play any role, only power dissipated in 30 Ω resistor.
But it R = 0, then power dissipated in 16 Ω resistor also.
