Question

What is the voltage in a circuit that has a current of 10.0 amps and a resistance of 28.5 ohms?
A.
2.85 volts
B.
285 volts
C.
0.35 volts
D.
18.5 volts

Answer 1

To calculate the voltage in a circuit using Ohm's Law, you can use the formula:

\[ V = I \times R \]

where:
- \( V \) is the voltage in volts,
- \( I \) is the current in amps,
- \( R \) is the resistance in ohms.

Given:
- Current \( I = 10.0 \) amps
- Resistance \( R = 28.5 \) ohms

Plugging in the values:

\[ V = 10.0 \, \text{A} \times 28.5 \, \text{Ω} = 285 \, \text{volts} \]

So the voltage in the circuit is **B. 285 volts**.
