Tecnología Electric Qualities
CIRCUIT IN PARALLEL
2 o + elements connected for differents wires
Formulas
V = I . R
I = I1 + I2
P = V . I
V = V1 = V2
1/R = 1/R1 + 1/R2
Several ways to come to a pole
ELECTRIC CHARGE
number of electrons in the circuits
Q
Coulomb (C)
RESISTANCE
opposition to the motion of electrons
R
Ohm (O)
R=l/S
l = length (m)
S = surface (m2)
ELECTRIC ENERGY
energy of the circuit
E
Joule (J)
E = V.I.t
ELECTRIC POWER
energy of the circuit per unit of time
P
Watt (W)
P = E/t
CIRCUIT IN SERIES
1 way to come to a pole
2 o + elements connected for the same wire
Formulas
R = R1 + R2
V = I.R
P = V.I
I = I1 = I2
AN ELECTRIC CIRCUIT
Is a way which electrons flow between the parts of the circuit which are connected by a wire
