Ohm's+Law

Chapter 6: Ohm's Law

· Basic Calculations o Ohm’s Law, states that current is directly proportional to voltage and inversely proportional to resistance. o ** Current ** = voltage/resistance o Current and voltage are **directly** proportional. o Current and resistance are **inversely** proportional. · Powers of Ten o Metric Prefix 1. Milli 2. Micro · Finding Voltage o Transposing simply means changing the equation from one form to another. o E=IR · Finding Resistance o R=E/I · Using Ohm’s Law o I=E/R <span style="font-family: 'Courier New'; font-size: 14pt; mso-fareast-font-family: 'Courier New'; msofareastfontfamily: 'Courier New'; msolist: Ignore;">o E=IR <span style="font-family: 'Courier New'; font-size: 14pt; mso-fareast-font-family: 'Courier New'; msofareastfontfamily: 'Courier New'; msolist: Ignore;">o R=E/I <span style="font-family: 'Courier New'; font-size: 14pt; mso-fareast-font-family: 'Courier New'; msofareastfontfamily: 'Courier New'; msolist: Ignore;">o E- Voltage <span style="font-family: 'Courier New'; font-size: 14pt; mso-fareast-font-family: 'Courier New'; msofareastfontfamily: 'Courier New'; msolist: Ignore;">o R- Resistance <span style="font-family: 'Courier New'; font-size: 14pt; mso-fareast-font-family: 'Courier New'; msofareastfontfamily: 'Courier New'; msolist: Ignore;">o I- Current
