Alternating Current

Question:

Determine the current passing through a resistor circuit comprising of resistor of resistance 20 Ω and a voltage source supplying V=10 Sin 10πt V.

Options:

0.5 A

0.5 Sin 10πt 

0.5 x 10-3 Sin 10πt

0.5

Correct Answer:

0.5 Sin 10πt 

Explanation:

I = \(\frac{V}{R}\) = \(\frac{10 Sin 10πt  V}{20  Ω}\)
