DIR
E(J) = P(W) x t(s) energy transferred= power x time
P(W) = V(V) x I (A) power=potential difference x current formulas
P(W) = I^2 (A) x R (Ω) power=(current x current) x resistance
ALTERNATING AND
regularly change direction DIRECT CURRENT
ALTERNATING CURRENT (ac)
he positive and negative values indicate the
T
direction of current flow
NA
