Answer: 30Ω

Explanation:

Given that,

Electrical potential (V) = 120V

Current drawn (I) = 4A

Effective resistance of your computer (R) = ?

Recall that voltage is the product of current and resistance

i.e V = I x R

120V = 4A x R

R = 120V / 4A

R = 30Ω (The unit of resistance is ohms, and its symbol is Ω)

Thus, the effective resistance of your computer is 30Ω
