Ohm's law and resistance


Gina connects a power supply providing voltage, V, equals, 5, point, 0, space, start text, V, end text, across a resistor of unknown resistance.
With an ammeter, she measures a current, I, equals, 0, point, 20, space, start text, A, end text, across the resistor.
What is the value of the resistance, R?
R, equals
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
