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

1 answer

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.
