Find the current drawn from source in each of the circuits as given below

Explanation

i) Current in inductor lags the voltage by `pi//2`.
Current in capacitor leads the voltage by `pi//2`
The phasor diagram can be drawn as

By vector algebra, current from source = 0.2 A
Current in resistor is in phae with voltage. The phase diagram can be drawn as

So, net current drawn from the source is
`i=sqrt((0.3)^(2)+(0.4)^(2))` = 0.5 A
Current from source = 0.5 A
