Ohms law & Power

Bio Med Tech course 1

Ohm's Law states? Current is directly proportional to voltage and iversely proportional to resistance.
What is voltage/potential difference? Voltage is the elctrical pressure or force that makes current flow in a circuit
What happens if voltage increases? Current also increases, provided resistance stays the same.
What is current? Current is the flow of electrons through an electrical circuit.
What happens if current flow increases? Voltage increases and decreases as resistance increases
What is resistance? Resistance is the opposition to current flow.
What happens if resistance increases? Current decreases, provided voltage stays the same.
What are the unit of measure for each quantity and also what is the symbol? Voltage "V or E" (Volt=V), Current "I"(Ampere A) Resistance "R"(Ohm Ω)
What is the formula for Current in Ohm's Law? I=V/R
What is the formula for Resistance in Ohm's Law R=V/I
What is the formula for Voltage in Ohm's Law? V=IxR
If you have two known electrical quatities what can you do? You have find the one unknow electrical quanitity
What can you use to help recall the Ohm's Law? The VIR circle
Ohm's Law is what? The relationship between voltage, current, and resistance
Voltage can by symbolized by using the letter (E) what does (E) stand for? Electro-motive force
What is Power? Power is how much work an electrical circuit performs
What is dissipation? The heat given off that is developed across a resistance

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
