Question

In a wall outlet with a resistance of 3.7 ohms and a voltage of 110V, what is the current flowing into the outlet?
A. 113.7 A
B. 29.7 A
C. 407.0 A
D. 0.04 A

Answer 1

To find the current flowing into the outlet, we can use Ohm's Law, which states:

\[
I = \frac{V}{R}
\]

where \( I \) is the current in amperes (A), \( V \) is the voltage in volts (V), and \( R \) is the resistance in ohms (Ω).

Given:
- Voltage \( V = 110 \) V
- Resistance \( R = 3.7 \) Ω

Now substituting the values into the formula:

\[
I = \frac{110}{3.7} \approx 29.73 \, \text{A}
\]

So the current flowing into the outlet is approximately 29.7 A.

The correct answer is **B. 29.7 A**.
