Basic Electronics Flashcards

Question 1

Q

Ohms Law
Calculate Voltage (E)

Answer

A

E = I x R
Voltage (E) = Current (I) x Resistance (R or Ω)

Question 2

Q

Ohms Law
Calculate Current (I)

Answer

A

I = E / R
Current (I) = Voltage (E) / Resistance (

Question 3

Q

Ohms Law
Calculate Resistance (R or Ω)

Answer

A

R = E / I
Resistance (R or Ω) = Voltage (E) / Current (I)
