Ohms Law

• What does Ohm's Law link together in a circuit?

  Voltage (V), current (I), and resistance (R)
• What is the formula for Ohm's Law?


  $V =$$I \times R$
• What does V represent in Ohm's Law?

  Voltage (in volts, V)
• What does I represent in Ohm's Law?

  Current (in amps, A)
• What does R represent in Ohm's Law?

  Resistance (in ohms, Ω)
• What happens to current if resistance remains constant and voltage increases?

  • Current (I) will increase
  • This is due to the direct relationship between voltage and current in Ohm's Law
• What happens to current if resistance increases while voltage remains constant?

  • Current (I) will decrease
  • This is due to the inverse relationship between resistance and current in Ohm's Law
