How much current will a 120-v wall outlet oush through a 20-ohm circruit?

Answer 1

A 120V wall outlet will push 60 amperes through a 20 ohm circuit, generating 7200 watts of power in the process.

That is a lot of power.

Let me repeat.

That is a lot of power.

Don't even think about trying this in the lab. You are talking about serious energy here and risk of fire and injury or death,

Besides, the question is loaded. There is no 60 ampere 120V wall outlet, The closest you could come would be a 60 amp 240V range or water heater outlet.

Think about this very carefully. Stick a 20 ohm resistor in an ordinary 120V outlet, turn it on, and the resistor and the breaker are going to rush to beat each other before one trips or the other blows up. What if the circuit breaker failed? What if someone got hurt? What if someone died? Think about calling your parents and saying you've been arrested and charged with negligent murder, and that your entire career is ruined.

Answer 2

The simple answer is V=IR => I=V/R => I=120/20 => I=6 amps.

Answer 3

The formula you are looking for is I = E/R.

Answer 4

6 Amps I=E/R

Answer 5

6
