Ohm's Law is given by the equation V = IR where V is voltage in watts, / is current in amperes, and R is resistance in Ohms. A lamp needs 0.5 amperes. Which equation can be used to determine the voltage for a given amount of resistance?

A. V = 2R
B. V = 0.5R
C. V = 0.5/R
D. V = R/0.5

Answer:

B. V = 0.5R

Step-by-step explanation:

Given:

  • V = IR

Where:

  • V is the voltage
  • I represent the current in amperes
  • R represents the resistance in Ohms

V = IR

I = 0.5 amps

V = 0.5R

V/R = 0.5

Therefore, from the given options, Option B matches the correct answer.
