Take the '150' part of the function (the peak voltage) and divide it by the resistance, to get the current. I = V/R
i(t) = 30 sin(377t)
It's simple.

For a simple resistor, there is no difference in Sinusoidal or Direct Current. Simple Ohm's law may be used to find the current expression.
If V is the voltage across the 5 Ohm resistor then the current
I = V/5 Amp.

contemporary is j*voltage / reactance of capacitor. This reactance looks 2.5 out of your question.for that reason contemporary is j*utilized voltage divided via 2.5. If utilized voltage is two.5, contemporary is a million amp. j shows that the present leads the voltage via ninety deg.

seems an odd question to me, resistor is a dc component,
V = IR be interested to see other answers
