Current ,voltage Flashcards
What is current
The rate of flow of charge through a conductor
What is the symbol of current
I
How do u calculate current
I = Q
——-
🔺t
What does
Q represent
🔺t represent
I represent
Q represent— charge in C
🔺t represent —— time in secounds (🔺delta)
I represent —— current in Amperes(A)
Hwo do u calculate charge
Q= I x 🔺t
VOLTAGE
WHAT IS THIS
work doen per coulomb of charge as it moves from one point to another
VOLTAGE
How do u calculate voltage
V= W

VOLTAGE
Hwo do u calculate enegry (w)
W= VQ
What does
W represent
Q Represent
V represent
W represent— energy in Joules (J)
Q Represent —- charge in C
V represent —- voltage in volts (v)
What’s used to measure current amd how is this connected
An ammeter is used to calculate current
An ammeter is connected in series
What’s used to measure voltage amd how is this connected
An voltsmeter is used to calculate voltage
An voltsmeter is connected in paralell to the resitor
what does the volts meter record
it record the amount of voltage used by the resister
